I've known about aphantasia for a long time, but there is one question I keep coming back to: Is it a skill issue?
When I was in second grade, our teacher asked us to close our eyes and imagine a pretzel. I closed my eyes and tried to will a pretzel to appear as an image, and I failed miserably. All I saw was darkness and faint squiggles. I didn't understand why so many of my classmates said they could "see" the pretzel with their eyes closed.
Later on, I realized that my mind's eye doesn't actually work like that. It's not like turning on a projector screen against one's closed eyelids and magically seeing things that aren't there. The imagery exists on another plane, such that I can visualize an apple with my eyes open or closed, because what I am "seeing" has nothing to do with my eyes themselves.
Which makes me wonder whether people who think they have aphantasia might not be missing a mind's eye, but rather are unaware of how to active it.

I have aphantasia in both visual and audio forms. And I can tell you audio aphantasia is wild.
I cannot hear a song in my head if my life depended on it but then there are triggers that extract it music it.
Examples: "who let the dogs out" (I remember rhythm but not the music). I play piano for almost 2 years but I have no idea what's the each sound is. It gets even better. Even though I play and record [0] I can't remember my own compositions. They usually come back to me as a play on hands and not on audio.
I thought I was music deaf for the most of my life. My music teachers mocked me in my youth showing me as an example of someone with zero hearing.
My latest music teacher discovered that I actually have absolute hearing skill but... can't recall sound in my head. So I sense even slight shift in toning (e.g. given few variations of same melody I can tell which one is the original tuning) but I can't reproduce it.

I know someone with aphantasia. It's absolutely wild to me that he can't see things in his head. Totally alien from my perspective, since I'm at the opposite end of the spectrum. I see what's in my head so vividly that I often won't see things in real life which are right in front of me.
But what's even more wild to me is the people leaving comments refusing to believe that different people are actually different. Refusing to believe aphantasia or hyperphantasia exists. Refusing to believe that other people are telling the truth when they describe their experiences. Insisting that everyone is the same, actually, and anyone who thinks differences are real must be confused or misunderstanding something.
I guess these are both types of cognitive disability... but I know what aphantasia is called. Not sure what the other thing is called, but I'd imagine it's something which sounds pretty unflattering.

For folks that are thinking this is just semantics or qualia, the site mentions this:
"We can also see activation in the visual cortex during fMRI studies, the area in the brain that processes images from the eyes, further suggesting actual visualization."

Also, Aphants lack pupil response when asked to imagine dark/bright scenes: https://www.sciencedaily.com/releases/2022/04/220420092150.h...

It would take a lot to convince me that aphantasia or phantasia actually exist.
Let's talk very specifically about the afterimage test here. Can anyone confirm that they have this ability, which specifically is to superimpose imagined objects inside your actual field of vision? If the answer to this is yes, then okay, I guess I have aphantasia. But none of the other criteria seems to apply.
I can imagine a song, and "hear" it in my "mind's ear", but I am not confused about whether it is occurring through my ears or just in my brain. I can easily imagine the tones and voices and tell you what the bass line sounds like, etc.
My visual imagination works the same way -- I can't make the object appear in my field of vision any more than I can make sounds appear in my field of hearing, but I can definitely imagine the visual aspects of it. If you tell me to imaging an equilateral triangle, I can put it there in my mind's eye, and if you tell me to attach another equilateral triangle to it I can see the resulting parallelogram. But I can't actually *see* it.
It would take a lot to convince me that phantasia or aphantasia actually exist, and nothing I see on this webpage convinces me.
