My boyfriend used to say that he would never read a book more than once, because he already thoroughly pictured the whole thing. But when watching a movie, he would catch new things on every rewatch. I never understood until now.

I can watch a movie in my head on demand. I thought this was something everyone can do!

Unfortunately doesnt work for movies I haven't seen ;)

Same. And when I think back about an old book I read, I remember the visuals rather than the words.
I couldn't tell you the names of all the characters in a book I read 10 years ago, but I can describe the 'scenes'. All the places they went to, things they saw, and the things I saw them do.
