I myself only just found out that aphantasia exists and that it isn't normal to have it. Like you, I'm not a big fan of literature or poetry, I like the stories but there isn't really a sense of immersion with most books. interestingly though, I do really like film, I'm studying at a film school right now so I can, hopefully someday, make a career out of filmmaking. Your post really made me ask myself if more people with aphantasia have a stronger passion for visual art than for written art and if, without aphantasia, I might have wanted to write books instead of making films. I just have so many questions about it right now and it has been really interesting and helpful for me, reading all these stories about the experiences of others with this. I think this might also be part the reason I was worse at maths and reading than most of my peers when I was in elementary school and even for a big part of high school. I always had to just keep on repeating and repeating everything until it was stuck in my brain at maths and I still read, and talk, a lot slower than most people. So yeah, my head is filled with thoughts about all of this right now, just now visual ones.
