I only recently (last few years) discovered that aphantasia is a thing. Before that I thought that when people were talking about "mind's eye" they were using a figure of speech that was totally unrelated to being able to create images in your head. I am a decent artist. I can sketch out the layout of a building after having been in it a short time, including identifying exits, etc. (maybe I should thank my CIA dad for that one) But I still can't recall images on demand. It's very strange. I always wondered if it was related to whatever brain malformation that caused my epilepsy. I also wondered if the genetics that caused my (admittedly self diagnosed) aphantasia was related to my brother's ability synesthesia. The brain is remarkable.
