You know, I have learnt that I have aphantasia several years ago and it opened my eyes to many things. I have thought that people say a lot of things metaphorically.
- Imagine a beach when meditating
- If you are nervous about giving a presentation, imaging that the audience is naked
- Count sheep in order to fall asleep fast
- Undressing someone with your eyes
- Visualising what is happening in the book you are reading.
I was completely sure that these were just metaphors. Imagine my shock when I realised that the majority of people can actually DO IT.
FeistySkink · 2026-08-27 14:09:20 UTC
Yeah, I never got the "don't think about the red hammer/apple" joke. Ok, done. Now what? For me thinking/imagining is an active process.
croisillon · 2026-08-27 14:33:05 UTC
and yet i believe it was Nietzsche who said something along the lines of "we don't think, we are thought" because for him (as for people without aphantasia) thoughts come whether you want it or not
faeyanpiraat · 2026-08-27 14:18:10 UTC
Its a lot of undressing in one comment :)
audidude · 2026-08-27 14:19:10 UTC
I didn't understand flashbacks in movies until about a decade ago when I realized I had it. What a corny and lazy story-telling-tool I'd tell myself.
christophilus · 2026-08-27 14:38:21 UTC
Oh. Interesting. I’m the same. Are those flashbacks actually a real thing people experience? I had also assumed it was just movie gimmicks.
audidude · 2026-08-27 14:45:08 UTC
They are real for some. I have Aphantasia but my wife has Hyperphantasia so we compare notes often. Each of us are at the edge of the spectrum.
stephen_g · 2026-08-27 14:54:23 UTC
Oh that's interesting. I feel like my visual recall/imagination is probably slightly below average but that I have incredibly unusually vivid auditory imagination and recall. I’ll have to read into hyperphantasia, I wonder if having one strong sense but average or below average in others is common or unusual?
stephen_g · 2026-08-27 14:50:41 UTC
I mean, yeah, I can sort of replay things that happen in my head (obviously it’s nowhere as vivid as real life but still imagining through things I saw), and then sometimes I do realise you saw something significant that I hadn’t realised when I do so. So if that’s what you mean by flashbacks, then yes?
nephihaha · 2026-08-27 18:41:05 UTC
Yes, unfortunately they are. I say unfortunately because they are often connected with trauma. When something goes very badly, those memories can go cycling around one's head. PTSD can do that too. Some people relive wars years after they happened. It's very real.
vidarh · 2026-08-27 14:52:55 UTC
I still find it a lazy story-telling tool, even in writing. It feels like an admission you can't find ways to weave the disclosure into the "present day" of the story in a natural way. Though, the notion that others can imagine these things if described to them makes it at least somewhat more understandable.

> - Visualising what is happening in the book you are reading.
This one is absolutely brutal. Even having a basic understanding of this condition could have changed my trajectory related to anything involving fiction during school. Having every character in a book visioned as a gray amorphous blog really does make it a difficult. And realizing only later that I was the only person in class experiencing this leaves me feeling so much regret and sadness.
pm215 · 2026-08-27 14:40:40 UTC
FWIW, I have always and still do enjoy reading fiction, and I never visualize what's happening in the book. I just read the words and enjoy the story...
Noaidi · 2026-08-27 14:41:45 UTC
Yeah, I hear this. Reading fiction was difficult for me because it was hard to distinguish and keep track of characters. I would find myself voicing the same voice for all the people in the story.
sixothree · 2026-08-27 14:55:42 UTC
It's important to keep track of characters when your final grade depends on it. Dialog was a bit difficult too because it was easy to lose track of who was speaking. What's interesting is that I remember enjoying reading when I was young. But that changed around 10 years I think.
vidarh · 2026-08-27 14:57:44 UTC
I love reading fiction despite my aphantasia (and writing it), but learning I had it made it make a lot more sense why I find sensory descriptions relatively uninteresting unless the prose itself is beautiful. I'll often skip descriptions of places or people because it gives me nothing.
mercutio2 · 2026-08-28 00:23:53 UTC
For me, just different, not harder. But maybe the problem is you got some gray blobs, and I got nothing? If anything, my sense is that the absence of imagery makes book reading much easier for me. At least for plot and abstractions.
I'll confess I always skip over the described imagery in most written works, though, so it's not like I'm missing zero.
I do read about 6x faster than my wife, with better recall for the (non-visual) details. Not sure how much of that is my wife reading slow, I have many non-aphantasiac friends who read as fast as I do.
pjerem · 2026-08-27 14:27:43 UTC
I was also shocked and a few minutes after i completely forgot. It's like, "ok, I can't miss something I've never had".
And I was hugely comforted in this position when I learnt that "normal" people hear a fucking real voice in their head. I hear nothing and that's totally fine :D
tpoacher · 2026-08-27 14:29:32 UTC
Same. This, and also the fact that it is also very highly associated with SDAM (Severely Deficient Autobiographical Memory) -- which I also have.
And also, reasonably associated with ADHD -- which I also have, but only recently realised and assessed for at the tender age of 46.
The SDAM is particularly useful to be aware of, otherwise you go crazy trying to understand why you remember how much your local pizza cost back in 1999, but otherwise vast areas of your life are as if they've been smeared by a blur filter. Let alone trying to explain it to a spouse who mistakes it for lack of interest / commitment.
Noaidi · 2026-08-27 14:51:11 UTC
Aphant and SDAM are linked with many neurological disorders. I have Schizoaffective Disorder Bipolar Type and OCD.
I normally have no autobiographical memory, but once I went to a weeklong meditation retreat and around the second day it sorta all showed up at once.
Anecdotal but perhaps interesting.
xerox13ster · 2026-08-27 17:14:25 UTC
Anecdotally, ADHD has nothing to do with this. Or rather, it has as much to do with aphantasia as aphantasia has to do with how prolific a reader someone is.
My ADHD used to make me constantly daydream and disappear mentally into incredibly vibrant internal worlds and it regularly impacted my ability to focus on schoolwork because I would draw flipbooks of what I was seeing.
I can sharply visualise autobiographical memories from when I was 6 months old of me crawling on the dining room floor and have had aunts and uncles confirm the shape and color of the chairs around the dining table on my left, the curling of the woodwork on the china cabinet to my right, the paisley pattern of the runner rug leading from the dining room to the den that I just crawled onto and can still feel the fibers on my knees. I left that house to never return when I was a year and a half old, and never saw pictures of it either.
On the other hand, I also have dissociative amnesia from everything that happened after that 1.5 year mark, so a lot of 5-10 is a huge bubbling black cauldron that occasionally burps out an autobiographical memory of some traumatic shit, or some mundane memory tangentially connected to something traumatic.
This to say, I would be more willing to accept a connection between aphantasia and SDAM, since you can't, with the same fidelity, reencode memories you can't visually recall, than I would be to accept that ADHD has anything to do with aphantasia at all, from my position on the other end of the mental visualization/autobiographical recall spectrum.
mohamedkoubaa · 2026-08-27 22:23:02 UTC
I didn't realize they were correlated. I have total visual and auditory aphantasia and can count childhood memories on one hand. But I have great semantic memory and could probably win a game of jeapordy.
thirdtruck · 2026-08-27 22:41:50 UTC
We strongly suspect we have SDAM as well and only more so after reading your description here. Only got diagnosed with ADHD a few years ago and as on the autism spectrum this year, here in our forties as well.
This whole topic fascinates us in no small part because we've gained or regained marked visualization capacity within the last year or so. Our change unequivocally correlates with our escape from and ongoing recovery from a long-term abusive relationship and all the dissociation that required of us and caused in us. That and no doubt some pharmacological assistance. It's been a wild ride, to remember having greater powers of visualization and then to come back into them.
ctxc · 2026-08-28 04:04:30 UTC
Thank you for your comment! It was useful. Found this that helped me look through the signs
Yeah, most people can do it, but the image is far from photo or video. They are mostly vague and lack lots of details. So, it's really not much difference.
graeme · 2026-08-27 14:40:13 UTC
From what people report some can see a full picture.
feverzsj · 2026-08-27 14:46:52 UTC
Photographic memory is very rare.
NoGravitas · 2026-08-27 17:01:08 UTC
There is a fairly wide spectrum short of photographic memory, though. I can see a fair bit of detail in mental imagery, but only if I trade off other things like the size of the area I'm imagining, or how long I can hold it in my mind.
perrygeo · 2026-08-27 14:59:19 UTC
I thought "count sheep" just meant "please just go the f*k to sleep, kid". Literally counting sheep was too absurd. At the risk of sounding obvious, there are no sheep. No amount of trying to conjure pictures of sheep would work. I was very confused by this as a kid.
Later in life, the realization moment came when I was watching a TV show, a police procedural where the witnesses described the suspect. Police were able to use the descriptions to make an accurate sketch. "Yeah right, like anyone could recall those details". I was convinced it was a Hollywood trick.
My friends looked at me funny and proceeded to describe the faces, clothing, etc. of off-screen characters with stunning accuracy. That's when I learned other people can recall (or even conjure) visual images and read them like photographs.
dooglius · 2026-08-27 18:38:03 UTC
I thought the point of counting sheep was to do something boring and repetitive that puts your brain into a relaxed state
perrygeo · 2026-08-27 20:44:08 UTC
Visualizing a sheep is not something I can even do once. Let alone repetitively until it gets boring. Being asked to visualize is quite frustrating and confusing - especially to a little kid not sure exactly what he's supposed to be "seeing". Hardly relaxing.
dooglius · 2026-08-27 21:49:23 UTC
I don't think you actually had to visualize the sheep for it to work, I never thought of that as being explicitly required
davidsojevic · 2026-08-27 14:59:33 UTC
I only learned about aphantasia a few years back and, like you, so many things in my life just clicked when I realised I was an outlier.
I could never relate with people when we'd read a book that had become a movie and they're like, "but they're not at all how I imagined them" and all I could think was "but the person in the movie has the exact characteristics described in the book!"
When people would ask me to imagine something then ask questions about it, I'd basically just be deciding details on the fly and then retaining them in a list. For example, if you said, "think of a car," inside my mind is just "a car" on repeat. Then if you asked me what colour it was, I might decide "red" and my mind is now, "a red car", etc.
wmorgan · 2026-08-27 14:30:45 UTC
An interesting test for kids that I stumbled upon. I’ll play them the audio of How the Grinch Stole Christmas, when we’re the car or whatever. So all the gags in that TV special are visual. Nevertheless my kids go nuts laughing from the back seat, at the right parts. What we’re all listening to is just instrumental, but they’re seeing all the gags. I wonder if you tried it with a kid with aphantasia. Would they laugh?
Noaidi · 2026-08-27 14:37:06 UTC
We still have memory, it is just not visual. I forget what they call it, I think it is structural memory. But yes, we certainly laugh. It is only visual memory loss, not memory loss.
The only test they have somewhat developed is a pupil test. When you tell someone with Aphantasia to imagine an apple their pupils do not change.
Aphantasia is about the mind's eye, not visual memory. Many people with aphantasia can still remember visual/spatial details of memories, they just can't see them. Not sure if those had to be recorded at the time of the memory or if they can be derived later, though. Based on some cursory research, it's not particularly uncommon for aphantasics to build a habit of intentionally making spatial observations in the moment for potential recall later.
physicalecon · 2026-08-27 14:51:28 UTC
If you take something like the “draw a bike” test, I have to wonder if the “normal” folks have any visual memory.
It’s always been curious to me that there’s this idea that people can “see” anything they wish, but then do not know what common objects look like. Whereas I’d wager any aphantastic would nail that particular test.
LoganDark · 2026-08-27 14:53:42 UTC
When I (not aphantasic) see something like a bike, I see characteristics of it but I don't imprint the entire bike as a whole. Which means that, were I to draw one, I'd have to re-derive aspects of the bike that I didn't bother to memorize, because they haven't been important to my understanding of bikes. My visualization of the bike would be less precise in the areas that I haven't memorized, like in the precise layout of the frame or location of the seat/pedals or proportions or etc. I assume that someone more familiar with bikes, who has memorized more details of a bike, would be better than I am at drawing a bike.
Noaidi · 2026-08-27 14:33:28 UTC
Thank you for this post. I have read several guides but this one is great and not just for me. I have aphantasia and Severely deficient autobiographical memory (SDAM) which often go hand in hand. Glad to have something I can give to people so they understand when I never remember their name.
It is a weird thing to discover you have this. It has really added more difficulty to my already difficult life neurologically speaking.
What I find interesting is that I have closed eye hallucinations. That is I do see things sometimes when I close my eyes but the things I see are not in my control. My psychiatrist told me that is because they are two different pathways and that is why we can still see dreams.
drakonka · 2026-08-27 14:35:58 UTC
When people talk about seeing something in your mind's eye, do they mean a virtual image actually appears _as if_ you are seeing it in place of the real world or the blackness of your eyelids? Like do they somehow replace the picture from the eyes to the brain with whatever they are trying to visualize in a sort of hallucination? Or do they still 'see' the blacks of their eyelids or the world around them while visualizing the apple but not _really_ seeing it?
christophilus · 2026-08-27 14:36:58 UTC
I don’t see anything, but I also wonder if this is semantics, and we are all describing the same phenomena with different language.
_dwt · 2026-08-27 14:42:45 UTC
I'm very convinced this is what's going on. Qualia are super hard to convey with language! If I had to guess these self-reported instruments are also measuring, indirectly, conscientiousness (do I _really_ see it? it'd be wrong to lie on a survey!) as well as neuroticism (oh God what does that mean? do I _really_ see it? do other people _really_ see it? am I broken?).
Noaidi · 2026-08-27 14:54:56 UTC
It is Qualia only until they can measure it. Which they can now. Blaming everything you do not understand on neuroticism? Might as well go back to dunking witches.
I'm not really sure what the hostility is about. That's an interesting study albeit small: 42 non-aphantasiacs and 18 self-diagnosed phantasiacs. If one really wanted to quibble I'm sure there are other possible confounding variables which could be involved in both pupil dilation and self-reported aphantasia. I'm not "blaming" neuroticism, I'm pointing out that these self-reporting surveys are subjective in a way that can be influenced by personality traits.
jibal · 2026-08-28 01:58:52 UTC
A lot of people here are insisting, with no evidence whatsoever, that a lot of other people are deluded, or are in it to make money, or for an ego boost, or to get pity, etc. ad nauseam ... so don't play dumb.
Aphantasia, hypophantasia, phantasia, and hyperfantasia are all real, per the evidence. Absolutely no evidence supports the contrary claim.
I won't respond further.
jtbayly · 2026-08-27 16:03:33 UTC
It’s very hard to prove, yes. But you need to deal with the association with SDAM, and the differences in outcomes on the https://aphantasia.com/study/vviq.
It is highly unlikely to just be semantics, because when it comes to visualizing complex objects as a non-aphantasic, the specific details spring forth unbidden as an image first, and then you attach the language, and it isn't the reverse order. I suspect also tests of visual memory of complex pictures should reveal similar things here, because e.g. language and other things don't really seem to be able to represent such details, and neurobiologically, there isn't much plausible other way your brain could be memorizing a complex photo without retaining / having activation patterns similar to the actual viewing (and this is what we see in fMRI studies).
If you are careful at noticing your thoughts (and not aphantasic), you can also notice if you are a highly visual thinker, you might sometimes confuse certain memories of things (spellings, place names, other things) that are similar only visually, but not logically or in any other sense modality representation. This would suggest the representations are genuinely visual in these cases.
But yes, no way to be 100% certain, but the "it is just semantics" case is very weak and can't explain much.
_dwt · 2026-08-27 17:38:35 UTC
I am reasonably confident I am not aphantasiac in the sense described here. My apple is red with some nice green mottling, dust, etc etc. I can see my wife and children in detail in my "mind's eye". As a child people told me I had a "photographic memory", which I also think is sort of "fake" or semantic, but nonetheless: I can remember images I have seen with visual detail and I can imagine hypothetical objects "visually". I still think many self-diagnosed aphantasiacs are tripping on the semantics of wording in a self-report survey, because I could easily talk myself into the other label based on second-and-third-guessing "but what does it mean to _see_ something I'm imagining?" etc. If there is a group of people with an actual quantifiable brain difference, I suspect it is much smaller than the group of "all self-diagnosed aphantasiacs".
D-Machine · 2026-08-27 17:46:47 UTC
Yeah, you don't sound aphantasic to me then either. I am certain you are right some self-diagnosed aphantasics are caught up in semantics: psychology instruments in general are quite terrible, and certainly anyone that just does some self-report test and reads no further I could very easily see becoming confused here.
But the more a person thinks and read about it, especially given how much easier it is to find people writing and talking about it today, then I think the likelihood of being caught in such a semantic trap will go down a lot. Or at least, that should happen so long as one doesn't attach excessive moral value to or get bogged down in "identifying" as aphantasic/not.
defatigable · 2026-08-27 21:52:53 UTC
Ironically your comment has strengthened my belief that aphantasia is real and that I have it. :-)
The possibility of visualizing an apple with any of the details you describe is completely alien to me. Like, not "I can conceptualize something like that in my head but it's not SEEING", but "it is impossible for me to conceptualize that".
If you asked me to conceptualize an apple and asked me to add details like the color of it, whether it had a stem, etc. I would just be generating a mental checklist in my head. Vaguely like a running narrative, "I said it was a red apple. I said it had a stem. I said it had a bruise near the top."
But there's no sense in which I'm constructing a model in my head that I can consult, it's just a list of facts.
Every so often I've had discussions with people who do have a mind's eye and they've said something that just caught me off guard with its alienness. In your case the idea that when you imagine an apple it comes to you formed with a bunch of visual detail. I could only fill in details like that if explicitly asked (by myself or someone else). Or a friend saying casually "oh yeah I'm imagining her sitting over there to the left on that chair" - it had never occurred to me that people could visualize something with an actual location in space, or interacting with a real world object.
jibal · 2026-08-28 01:50:58 UTC
How could it be just semantics if I and others cannot do what you can? The comment you responded to said "I don’t see anything, but I also wonder if this is semantics, and we are all describing the same phenomena with different language" to which you responded "I'm very convinced this is what's going on." -- but what is "this"? They said that they don't see anything, which is by definition aphantasia, but you say that "I am reasonably confident I am not aphantasiac in the sense described here". You are clearly the one who is confused. If your self-report is accurate then people differ in this regard -- and we already know this from differing physical measures when people are tasked with visualizing.
The people who hold that it's just semantics and all minds are alike in this regard are just expressing a belief that has absolutely no evidence to support it and a great deal of counterevidence.
quickthrowman · 2026-08-27 14:49:47 UTC
Yeah, I’m convinced this is the case. Accurately conveying something like that (the qualia of mental imagery) to another person using words is more or less impossible, in my opinion. People like to label themselves and feel special, this is an easy way to do it.
Al-Khwarizmi · 2026-08-27 14:52:59 UTC
Yeah, I think I have aphantasia as I definitely don't see anything, but after reading a lot about it I still haven't totally ruled out that it's simply a big semantic misunderstanding with people that describe things in a different way.
All the easily accessible aphantasia tests (such as the one in this link) seem to rely on subjectively deciding whether you "see" or not. But this "seeing" seems to be a metaphor (even people who claim to be non-aphantasiacs will concede that it's not literally like seeing), so how do I know that other people aren't having essentially the same internal experience but choosing different words to describe it?
It also doesn't help that it doesn't seem to have any bearing on cognitive ability, or ability to perform tasks that one could effectively measure. I have never felt like I can't do something because I have aphantasia. I have seen people mentioning difficulty on problems where you need to mentally rotate a cube, but I can do that just fine - it's just that I don't "see" or "picture" the cube, but I still have the concept in my mind of the cube being in a certain orientation and that suffices to solve the task.
I have read that there are some tests for aphantasia that don't ultimately depend on introspection and vocabulary (e.g. pupils reacting to imagining something bright or dark, see https://pubmed.ncbi.nlm.nih.gov/35356890/) but I haven't found anything that I can do at home to be sure that I'm really aphantasiac and not just pessimistic about describing "inner images". If anyone knows such a test that one can do at home, I would be very interested.
slibhb · 2026-08-27 14:57:26 UTC
This is what I used to think. That "aphantasia" was just people arguing semantics about subjective experience. But my belief now is that if you think this way, you likely have aphantasia (I think I do).
A couple things that convinced me that the phenomenon is probably real:
1. I can visualize when I dream, or when I'm dozing/napping. But I can't while awake
2. I can "visualize" sounds, so I can hear a sound/song in my head and it's pretty much like actually hearing it. But I can't do this for imagery
Admittedly, neither of those is a smoking gun and I'd also be interested in a more objective test.
vidarh · 2026-08-27 15:01:49 UTC
This is my experience too. I have aphantasia for all intents and purposes but I have had one single experience years ago during meditation where I suddenly experienced "being in" a scene that was vivid and clear that I knew to not be real. It's nothing like when I "imagine" something and don't see anything.
It was also nothing like when I dream, where I too can visualise - it was much clearer.
It's clear to me that most of the time when people question that this is possible, it's an indicator they have aphantasia.
sixothree · 2026-08-27 15:03:14 UTC
I think this is a better self-test.
Visualize a ball on a table. Now imagine someone walks up to the table, and gives the ball a push. What happens to the ball?
Now, answer these questions:
- What color was the ball?
- What gender was the person that pushed the ball?
- What did they look like?
- What size is the ball? Like a marble, or a baseball, or a basketball, or something else?
- What about the table, what shape was it? What is it made of?
And now the important question: Did you already know, or did you have to choose a color/gender/size, etc. after being asked these questions?
drakonka · 2026-08-27 15:12:33 UTC
This is an interesting one and I just tried it. I could answer all the questions about the ball, but none about the person or the table other than them existing in a hand-wavy sense. But rather than informing any level of aphantasia, it seems more likely that I simply did not prioritize visualizing those other things past their rough properties, focusing instead on the ball.
Jtsummers · 2026-08-27 15:19:24 UTC
> it seems more likely that I simply did not prioritize visualizing those other things past their rough properties, focusing instead on the ball.
Right. Details come in, for me, based on:
- Familiarity with the subject. "Imagine your sibling playing ping pong". I can get a vivid image of my sister, the table, the movement of the ball during a game.
- Letting my mind wander, daydreaming style. More details will fill in as I imagine the scene for a longer period of time.
- Prompting. Once prompted to think about the person, details were added but the previous image (just a generic person and generic table) did not lead me to imagine anyone in particular or any details that could suggest a gender or other specifics.
And I don't know why anyone would expect differently. Not all imagined things are vividly imagined even if you possess the ability to do so, that shouldn't be a surprise.
davidsojevic · 2026-08-27 15:18:26 UTC
I could answer "the ball probably rolls off the table" and to everything else; I had no answer and would have to choose after the fact if pushed for an answer.
card_zero · 2026-08-27 15:33:19 UTC
But say you're overexcited and drunk, maybe then you think about all these extraneous matters, for fun and because you're not focused on the main question, and then you do have answers.
cassianoleal · 2026-08-27 16:37:52 UTC
Yeah so you probably have between what TFA describes as hypophantasia and phantasia.
card_zero · 2026-08-27 15:30:51 UTC
That's a test of how interested you are in random people, or indeed in visualizing things at all when not actually necessary.
LordGrey · 2026-08-27 17:38:23 UTC
You might need to take a person's background into account as well.
I, for instance, am an avid billiards player. A "ball on a table" naturally makes me think of a billiard ball on a billiards table. A whole host of detail was filled in for me, but all specifically in that context. I could answer some of the answers as if I could visualize, but most of them as someone who could not.
n = 1, I know, but sometimes it takes only one example.
idoubtit · 2026-08-27 17:53:45 UTC
Same here. I immediately visualized one of my juggling balls (the hard kind, pastel blue) on my kitchen table, so the scene was clear. But I was focused on the ball, so I only felt someone approaching and saw their hand pushing the ball, which rolled and fell.
I tried to visualise a scene with more unfamiliar objects (a box in the street then a flood wave arrives) and I also built the scene from my own memories. But I'm obviously biased after the first test.
With objects that I've never seen myself (e.g. a handgun), I have a hard time imagining them and placing them in my imaginary scenes.
card_zero · 2026-08-27 15:17:45 UTC
Those tests could also depend on some third thing, such as not believing that you're visualizing a bright light. I can't see their methodology. "Here, we show that the imagery pupillary light response correlates with objective measures of sensory imagery strength." Really, objective measures of how bright an imaginary light is, how on earth do they think they can measure that!? Was it like "we gave them a sheet of paper where they had to score how bright a light they were imagining, and the sheet of paper objectively existed so it was an objective test"?
Well anyway the whole concept, and the science, seems like a giant troll.
inigyou · 2026-08-28 03:28:13 UTC
If the concept of the mind's eye seems like a giant troll to you, you're either aphantasic or haven't connected the right dots. Can you remember a song? If so, can you do something similar with a picture?
inigyou · 2026-08-27 15:20:51 UTC
It's like a low-quality offscreen framebuffer, and if you can see things in a dream, it's like that.
drakonka · 2026-08-27 15:29:48 UTC
In a dream I actually am fully immersed and can see the entire world as if it was real. In a normal dream I assume the dream is the real world, and in a lucid dream it is vivid enough to feel, look, and sound like a real physical experience though I know it's not. But in a dream there is no real visual still being processed to compete with the dream visual, so surely it can't be exactly the same? If it's really like dreaming then TIL I may have aphantasia..
inigyou · 2026-08-27 15:35:13 UTC
In a dream I think I can see a whole world, but I actually can't. Upon closer inspection, only the relevant characteristics of the thing I'm "looking" at are actually "rendered" or "simulated", and the rest is filled in by a vague feeling of "yeah yeah trust me bro there's a world there"
It's basically like AI Minecraft. You know, that project where someone trained a stable diffusion model to predict the next video frame based on the previous frame and the player inputs. Then people started speedrunning it, like by looking down into a lava pool and back up, now they're in the Nether (underground lava dimension). That's how I think dreams are, except you don't even get a full video frame, just one object of focus.
drakonka · 2026-08-27 15:40:03 UTC
That makes sense and there are some philosophical questions about whether our own world may be rendered similarly to a video game - do the things not within our senses actually render? Or do they only 'load in' when we observe them?
For me the real surprise is the fidelity of the visual I _do_ get. Sounds, sight, and touch feel just like real life (in lucid dreams especially now that I think of it). If the quality of our waking visualization is really meant to be the same as it is in our dreams, for me it is nowhere close.
inigyou · 2026-08-27 22:55:56 UTC
Our world exists. Don't overthink it. But dreams aren't real at alll, they just fill in a bare minimum of data and handwave the rest. Which is also what I was getting at with my visual imagination, although the rest isn't handwaved away at all - if I think of an apple on a desk I'm under no illusion there's any more than a ("low res") image of an apple and part of a desk.
mortenjorck · 2026-08-28 02:25:25 UTC
Ha, I was going to describe it the same way. The image is there in the buffer, you have full bit-level access to it; the only difference is that there's a firewall preventing it from being rendered to the primary display. Dreaming allows rendering it to a virtual display which is temporarily considered canonical.
I think the resolution and bit depth of that buffer is the aphantasia spectrum. Some people are working from a 160x120 1-bit image, for some it's 640x480 8-bit, and some can load up an 8K at 32-bit deep color.
inigyou · 2026-08-28 03:27:02 UTC
I don't know if everyone is like this, but low-res is not to be deemphasized. When another comment had a test about bicycles, I can see the shape of a bicycle frame, but I definitely can't see how many gears it has unless I zoom in on the gears (and I don't know how many gears a bicycle is supposed to have, but I can imagine any number up to about 5.)

> I have seen people mentioning difficulty on problems where you need to mentally rotate a cube, but I can do that just fine - it's just that I don't "see" or "picture" the cube, but I still have the concept in my mind of the cube being in a certain orientation and that suffices to solve the task.
As someone with probably some form of aphantasia, a cube is fine because it’s a simple shape with well defined simple mathematical rules that is easy to abstract and rotate. It gets more complicated with complex objects and that’s where visualizing things really matters. Here’s a question, can you accurately visualize a loved one’s face, see it in your mind and describe all the features if you were for instance talking to a police sketch artist. I couldn’t even do that for my daughter or my wife.
Al-Khwarizmi · 2026-08-27 17:14:27 UTC
I definitely can't - if I had to describe my wife or son, I would be hard pressed to go beyond very generic descriptors (long black hair, brown eyes, and so on), nothing useful to create an accurate sketch. And I wouldn't be able to draw them from memory even if I were good at drawing. This could also be explained simply by having bad memory for faces, though.
But yes, little bits of subjective introspective evidence (like that one, and also mostly ignoring visual descriptions in books, and the perception of having no mental images at all that is asked by the standard self-report tests, and so on) add up and make me 99.9% sure I have aphantasia. It's just that it would be nice to have the objective unambiguous external test, the silver bullet, to be totally sure that they're not a bunch of busses in a trench coat as so many honest beliefs are.
inigyou · 2026-08-28 03:29:08 UTC
note that many autistic people (overrepresented on HN) have face blindness which is (probably) a separate thing. They don't develop the specific specialized circuits for recognizing facial features.
nottorp · 2026-08-28 06:52:10 UTC
> All the easily accessible aphantasia tests (such as the one in this link) seem to rely on subjectively deciding whether you "see" or not.
I don't know. Have you tried the ball on the table test that's inside the article? What was your answer to the last question?
I have been wondering this as well. I took part in a study at the local university that seemed related to visualization ability. Aside from various questionnaires about imagining different types of objects, they had me do a test on a PC where I had to look at moving shapes for a few seconds at a time. The shapes would then disappear and I'd have to click on it when it reappeared in a new position a few seconds later. You were meant to be able to predict the location based on the shape's trajectory and could react faster that way.
I doubt it was trying to identify aphantasia though, since that seems like a task you could do well in even without being able to visualize the shape.
fellowniusmonk · 2026-08-27 16:53:49 UTC
I developed full aphantasia at 16 after being put under for a heart procedure.
My minds eye was somewhat diminished after a procedure at 11 when they put me in a twilight instead of fully under.
I have a sister younger who is 6 years younger, we used to play imaginary games all the time, few years ago she asked why we just stopped playing games and it was because I couldn't see the characters anymore.
I eventually recovered like, idk, a faint outline of my parents faces from before the surgery that I can kind of conjur.
It's not semantics.
ajkjk · 2026-08-27 17:08:34 UTC
I'm sure it's not, because most of the time I'm aphantasic and rarely I'm not and they're completely different phenomenological experiences.
andy99 · 2026-08-27 17:42:35 UTC
I’ve see no evidence it’s anything but this. I have no idea if I have it or not or just describe stuff differently. I think this is logically much more likely. It’s a “what does it feel like to be conscious?” or “is my red your red” kind of question. There’s no external benchmark, no way to objectively compare, so you just get a spectrum of reports about the same thing.
edgyquant · 2026-08-27 17:45:09 UTC
Sometimes I think so, I don’t visually see anything in my mind it’s all just thoughts about things like I can feel the image but can’t actually see it.
However I have taken psilocybin mushrooms and when I do I can literally visualize things in my mind as crystal clear as I can see the real world. So I think it isn’t just semantics
D-Machine · 2026-08-27 17:55:30 UTC
Then you are almost certainly aphantasic. "It is all just semantics" has to do some incredible acrobatics to make sense of so much language and reported experiences, and doesn't seem biologically plausible either.
Of course, we can never be sure, but from a theoretical and empirical standpoint "all aphantasia discussion is just semantic confusion" is not useful and a complete non-starter.
vehemenz · 2026-08-27 18:31:10 UTC
I have doubts about aphantasia as a legitimate phenomenon, but whether it is or it isn't, it seems likely that many of the positive reports are a result of a misunderstanding, semantic or otherwise.
D-Machine · 2026-08-27 18:43:47 UTC
Certainly some self-diagnoses (positive or negative) are definitely based on misunderstanding, much semantic, as I already agreed in this very thread: https://news.ycombinator.com/item?id=49468528.
randomImmigrant · 2026-08-27 14:37:05 UTC
For me the image in front of my eyes is not gone. I’m just not going to remember any details about it because my focus is inwards, on what my minds eye is showing me.
Comments
- Imagine a beach when meditating
- If you are nervous about giving a presentation, imaging that the audience is naked
- Count sheep in order to fall asleep fast
- Undressing someone with your eyes
- Visualising what is happening in the book you are reading.
I was completely sure that these were just metaphors. Imagine my shock when I realised that the majority of people can actually DO IT.
This one is absolutely brutal. Even having a basic understanding of this condition could have changed my trajectory related to anything involving fiction during school. Having every character in a book visioned as a gray amorphous blog really does make it a difficult. And realizing only later that I was the only person in class experiencing this leaves me feeling so much regret and sadness.
I'll confess I always skip over the described imagery in most written works, though, so it's not like I'm missing zero.
I do read about 6x faster than my wife, with better recall for the (non-visual) details. Not sure how much of that is my wife reading slow, I have many non-aphantasiac friends who read as fast as I do.
And I was hugely comforted in this position when I learnt that "normal" people hear a fucking real voice in their head. I hear nothing and that's totally fine :D
And also, reasonably associated with ADHD -- which I also have, but only recently realised and assessed for at the tender age of 46.
The SDAM is particularly useful to be aware of, otherwise you go crazy trying to understand why you remember how much your local pizza cost back in 1999, but otherwise vast areas of your life are as if they've been smeared by a blur filter. Let alone trying to explain it to a spouse who mistakes it for lack of interest / commitment.

Anecdotal but perhaps interesting.
My ADHD used to make me constantly daydream and disappear mentally into incredibly vibrant internal worlds and it regularly impacted my ability to focus on schoolwork because I would draw flipbooks of what I was seeing.
I can sharply visualise autobiographical memories from when I was 6 months old of me crawling on the dining room floor and have had aunts and uncles confirm the shape and color of the chairs around the dining table on my left, the curling of the woodwork on the china cabinet to my right, the paisley pattern of the runner rug leading from the dining room to the den that I just crawled onto and can still feel the fibers on my knees. I left that house to never return when I was a year and a half old, and never saw pictures of it either.
On the other hand, I also have dissociative amnesia from everything that happened after that 1.5 year mark, so a lot of 5-10 is a huge bubbling black cauldron that occasionally burps out an autobiographical memory of some traumatic shit, or some mundane memory tangentially connected to something traumatic.
This to say, I would be more willing to accept a connection between aphantasia and SDAM, since you can't, with the same fidelity, reencode memories you can't visually recall, than I would be to accept that ADHD has anything to do with aphantasia at all, from my position on the other end of the mental visualization/autobiographical recall spectrum.
This whole topic fascinates us in no small part because we've gained or regained marked visualization capacity within the last year or so. Our change unequivocally correlates with our escape from and ongoing recovery from a long-term abusive relationship and all the dissociation that required of us and caused in us. That and no doubt some pharmacological assistance. It's been a wild ride, to remember having greater powers of visualization and then to come back into them.

Later in life, the realization moment came when I was watching a TV show, a police procedural where the witnesses described the suspect. Police were able to use the descriptions to make an accurate sketch. "Yeah right, like anyone could recall those details". I was convinced it was a Hollywood trick.
My friends looked at me funny and proceeded to describe the faces, clothing, etc. of off-screen characters with stunning accuracy. That's when I learned other people can recall (or even conjure) visual images and read them like photographs.
I could never relate with people when we'd read a book that had become a movie and they're like, "but they're not at all how I imagined them" and all I could think was "but the person in the movie has the exact characteristics described in the book!"
When people would ask me to imagine something then ask questions about it, I'd basically just be deciding details on the fly and then retaining them in a list. For example, if you said, "think of a car," inside my mind is just "a car" on repeat. Then if you asked me what colour it was, I might decide "red" and my mind is now, "a red car", etc.
The only test they have somewhat developed is a pupil test. When you tell someone with Aphantasia to imagine an apple their pupils do not change.

It’s always been curious to me that there’s this idea that people can “see” anything they wish, but then do not know what common objects look like. Whereas I’d wager any aphantastic would nail that particular test.
It is a weird thing to discover you have this. It has really added more difficulty to my already difficult life neurologically speaking.
What I find interesting is that I have closed eye hallucinations. That is I do see things sometimes when I close my eyes but the things I see are not in my control. My psychiatrist told me that is because they are two different pathways and that is why we can still see dreams.
https://www.sciencedaily.com/releases/2022/04/220420092150.h...
Aphantasia, hypophantasia, phantasia, and hyperfantasia are all real, per the evidence. Absolutely no evidence supports the contrary claim.
I won't respond further.
It is highly unlikely to just be semantics, because when it comes to visualizing complex objects as a non-aphantasic, the specific details spring forth unbidden as an image first, and then you attach the language, and it isn't the reverse order. I suspect also tests of visual memory of complex pictures should reveal similar things here, because e.g. language and other things don't really seem to be able to represent such details, and neurobiologically, there isn't much plausible other way your brain could be memorizing a complex photo without retaining / having activation patterns similar to the actual viewing (and this is what we see in fMRI studies).
If you are careful at noticing your thoughts (and not aphantasic), you can also notice if you are a highly visual thinker, you might sometimes confuse certain memories of things (spellings, place names, other things) that are similar only visually, but not logically or in any other sense modality representation. This would suggest the representations are genuinely visual in these cases.
But yes, no way to be 100% certain, but the "it is just semantics" case is very weak and can't explain much.
But the more a person thinks and read about it, especially given how much easier it is to find people writing and talking about it today, then I think the likelihood of being caught in such a semantic trap will go down a lot. Or at least, that should happen so long as one doesn't attach excessive moral value to or get bogged down in "identifying" as aphantasic/not.
The possibility of visualizing an apple with any of the details you describe is completely alien to me. Like, not "I can conceptualize something like that in my head but it's not SEEING", but "it is impossible for me to conceptualize that".
If you asked me to conceptualize an apple and asked me to add details like the color of it, whether it had a stem, etc. I would just be generating a mental checklist in my head. Vaguely like a running narrative, "I said it was a red apple. I said it had a stem. I said it had a bruise near the top."
But there's no sense in which I'm constructing a model in my head that I can consult, it's just a list of facts.
Every so often I've had discussions with people who do have a mind's eye and they've said something that just caught me off guard with its alienness. In your case the idea that when you imagine an apple it comes to you formed with a bunch of visual detail. I could only fill in details like that if explicitly asked (by myself or someone else). Or a friend saying casually "oh yeah I'm imagining her sitting over there to the left on that chair" - it had never occurred to me that people could visualize something with an actual location in space, or interacting with a real world object.
The people who hold that it's just semantics and all minds are alike in this regard are just expressing a belief that has absolutely no evidence to support it and a great deal of counterevidence.
All the easily accessible aphantasia tests (such as the one in this link) seem to rely on subjectively deciding whether you "see" or not. But this "seeing" seems to be a metaphor (even people who claim to be non-aphantasiacs will concede that it's not literally like seeing), so how do I know that other people aren't having essentially the same internal experience but choosing different words to describe it?
It also doesn't help that it doesn't seem to have any bearing on cognitive ability, or ability to perform tasks that one could effectively measure. I have never felt like I can't do something because I have aphantasia. I have seen people mentioning difficulty on problems where you need to mentally rotate a cube, but I can do that just fine - it's just that I don't "see" or "picture" the cube, but I still have the concept in my mind of the cube being in a certain orientation and that suffices to solve the task.
I have read that there are some tests for aphantasia that don't ultimately depend on introspection and vocabulary (e.g. pupils reacting to imagining something bright or dark, see https://pubmed.ncbi.nlm.nih.gov/35356890/) but I haven't found anything that I can do at home to be sure that I'm really aphantasiac and not just pessimistic about describing "inner images". If anyone knows such a test that one can do at home, I would be very interested.
A couple things that convinced me that the phenomenon is probably real:
1. I can visualize when I dream, or when I'm dozing/napping. But I can't while awake
2. I can "visualize" sounds, so I can hear a sound/song in my head and it's pretty much like actually hearing it. But I can't do this for imagery
Admittedly, neither of those is a smoking gun and I'd also be interested in a more objective test.
It was also nothing like when I dream, where I too can visualise - it was much clearer.
It's clear to me that most of the time when people question that this is possible, it's an indicator they have aphantasia.
Visualize a ball on a table. Now imagine someone walks up to the table, and gives the ball a push. What happens to the ball?
Now, answer these questions:
- What color was the ball?
- What gender was the person that pushed the ball?
- What did they look like?
- What size is the ball? Like a marble, or a baseball, or a basketball, or something else?
- What about the table, what shape was it? What is it made of?
And now the important question: Did you already know, or did you have to choose a color/gender/size, etc. after being asked these questions?
Right. Details come in, for me, based on:
- Familiarity with the subject. "Imagine your sibling playing ping pong". I can get a vivid image of my sister, the table, the movement of the ball during a game.
- Letting my mind wander, daydreaming style. More details will fill in as I imagine the scene for a longer period of time.
- Prompting. Once prompted to think about the person, details were added but the previous image (just a generic person and generic table) did not lead me to imagine anyone in particular or any details that could suggest a gender or other specifics.
And I don't know why anyone would expect differently. Not all imagined things are vividly imagined even if you possess the ability to do so, that shouldn't be a surprise.
I, for instance, am an avid billiards player. A "ball on a table" naturally makes me think of a billiard ball on a billiards table. A whole host of detail was filled in for me, but all specifically in that context. I could answer some of the answers as if I could visualize, but most of them as someone who could not.
n = 1, I know, but sometimes it takes only one example.
I tried to visualise a scene with more unfamiliar objects (a box in the street then a flood wave arrives) and I also built the scene from my own memories. But I'm obviously biased after the first test.
With objects that I've never seen myself (e.g. a handgun), I have a hard time imagining them and placing them in my imaginary scenes.
Well anyway the whole concept, and the science, seems like a giant troll.
It's basically like AI Minecraft. You know, that project where someone trained a stable diffusion model to predict the next video frame based on the previous frame and the player inputs.
