Have a search for "aphantasia" and see if your experience matches.
The primary problem with this label is that this could include some people who see involuntary imagery (like people), but don't do what is essentially creative visualization. For those people, they "know" the experience of seeing things in mind.
Then there are the rest of us "aphants" that don't ever see images internally, at all. For the people I've found with this ability I would say none of them could hear things internally either. Not everyone has the ability to "rehear" things.
I spent a lot of years asking people about how they saw things internally and it just got weirder the more I asked. Eventually, I just decided that everyone thinks differently, with various "side models" that allow them to see, hear, think and even smell things that aren't real.
What about remembering things that you have already seen? Let's say I ask you to watch, for example, the Star Trek TNG opening sequence. Can you "rewatch" it?
I can. I can also sort of picture 'creative' images, to an extent.
However, conjuring up faces of people I've met is pretty difficult. Even my dog, which I find easier than people, can still take different shapes that are not real and I can't 'fix' it until I look at her again. If it is a person that I've only seldom met, I won't be able to recall the face at all, even if I can still recognize the person. It doesn't matter that I met the person a minute ago - if I don't make a very conscious effort to remember, I probably won't recognize them at all (and will definitely not recall the image). If I am under stress, that's even worse.
I've always chalked that up to 'being bad with faces', but there maybe something more at play, it seems.
For example, I cannot visualize the apple I have in my hand, even if I consciously study it for a few minutes and note out the shape and colouration before closing my eyes. However, I can visualize "an apple", I even get a choice between clipart version or realistic stock photo version of a red delicious or an granny smith. I cannot conjure up the faces of people I know, or even my own face, but I can bring up "young adult asian male" "elderly white female" etc.
When I looked up aphantasia, one of the test was "can you visualize waves hitting the beach" and I was wondering if the Toei logo because I can rewatch that anytime I want, but I can't visualize a generic beach with waves.
Anything "built up" from a mental concept, and seen as an image, would be exactly what I don't do.
While falling asleep I'm able to have hypnagogic visualizations. I do dream (but can't re-see the dreams) and psychedelics haven't produced anything much in the way of imagery. Maybe sounds and some slight alteration of the model, like movement or some slight color enhancement.
Or if shown two noses with different width bridges, can you point to the one that is closer to being right?
Police sketch artist scenes in movies and TV shows are incredibly abbreviated compared to reality, which often features a lot more iteration and discarded sketches precisely because a lot of people are in the "I'll know it when I see it" group.
