This is interesting. I can remember and hear sounds in my head, but can't visualize any images.
I wonder how common it is.
> A 2022 study estimated the prevalence of aphantasia among the general population by screening undergraduate students and people from an online crowdsourcing marketplace through the Vividness of Visual Imagery Questionnaire. They found that 0.8% of the population was unable to form visual mental images, and 3.9% of the population was either unable to form mental images or had dim or vague mental imagery
However I need to also say that after this year I sometimes can humm in my mind simple tunes like "Old McDonald", "Twinkle Twinkle" or that Looney Tunes piano melody that was always portrayed during rigging the piano, so it might not be hopeless.
It also impacts on mappers vs packers phenomenon and might by linked with alexithymia (which sounds rare but is quite common - especially for men).
Certain things I visualise as a matter of course, I give them colours and shapes etc., and in those things I do well at reasoning. But then I hear other people talk about how they visualise things like arithmetic and I notice they're much faster than me, I think because I'm not just "seeing" it, I have to actively "calculate" it.
