Ditto. I think. According to this article, that's not uncommon:

Many aphantasics dream in pictures and some see flashes of imagery under certain circumstances, such as just before they drift off to sleep. So although they can’t consciously control their mental pictures, the capacity itself doesn’t seem to have vanished.
https://www.newscientist.com/article/20 ... -my-brain/I had never heard of aphantasia before, but neither have I ever been able to visualize someone very clearly in my mind's eye -- certainly I can't visualize my husband when talking to him on the phone, for instance. I don't think I'm seriously faceblind, but I do have problems there and tend to recognize people more by how they stand and move, however that could be because I was legally blind for some time before they figured out I desperately needed glasses, and recognizing people by other traits was just easier.
Even though I know full well that I don't actually create pictures I can look at in my mind, it seemed odd to me that I would have aphantasia because I am aces at the rotating shapes part of an I.Q. test (where they give you a two dimensional image and you figure out which of the three "3-d" shapes would match it, or vice versa). But the article I linked to also says this:
Quote:
The challenge was to work out which images are the same as a guide image, only rotated, and which are not (see diagram). The greater the rotation, the longer it takes most people to perform the mental gymnastics and work out if there is a match. The theory goes that people rotate a mental image in their heads, and the more they have to manipulate it, the longer it takes to solve the task. [Person with aphantasia] apparently wasn’t doing that – yet he completed the challenge faster than average.
I could not visualize the guide image at all, however I could easily tell which of the three "rotated" items fit it, because two of the three were identical and so it had to be the third!

But maybe I'm quicker through that part of an I.Q. test because I'm doing that sort of thing?
I am particularly intrigued by this articles' speculation that at least some people with aphantasia actually do visualize something, it's just that they can't consciously access that visual image. The last time I got my driver's license, at one point in the vision test, the guy told me to read him off a list of letters in the box, and I could not see any. It was when they were testing only one eye, and I could see the light and the box I was looking into just fine -- but no letters. I figured he'd put the letters on the unlighted side or something, but he insisted it was set up right, and told me to recite the letters I thought were there -- which I did, and I passed. Even though I could
consciously see
not one letter. Obviously, the information was in my brain somewhere, and I could technically access it, but I could not access the visuals.
