>When I read a book, I kinda retain the "feeling" of the characters and maybe one or two visual traits. I can read thousands of pages of a character's adventures and I can maybe tell you their general body type and clothing - if they have an "uniform" they tend to wear.

Likewise. It even happens even with the people I know in detail such as family. If I try to project the image of my own son in my minds eye it is not clear and is always shifting, it's more of a feeling than a clear picture. Once, when I was a teenager, I was mugged and when at the police precinct they showed me a booklet with the common offenders in the area. After a few pages I could not remember what my mugger looked like. Always wondered how people manage to rebuild sketches of offenders not knowing as an aphantasiac it's nearly impossible.
