Eli5 why do people have Aphantasia?

Question

I recently got told that people are actually able to visualise images in their head, something which I cannot do, which brought me to the condition of Aphantasia.

Why is this something that I cannot do?

Answer 1

I realized I had this when talking to other people about how we think. I think in words, like I’m reading a story. No idea why though so I’d be very interested in any replies you get. Oddly I’m an artist, I describe what I want to paint or costumes I want to make with words first then draw what I’ve described. Somehow it works. I have autism and ADHD if that helps.
