Thanks again for taking the time to elaborate. I would not have assumed that being able to see an "after image" was related to this -- I had always assumed that that phenomenon was due to sensory overload. There is still a lot to learn :) I read that most people with aphantasia do have visual dreams [1], which I found interesting. In some period of my life I used to have nightmares about my grandmother (who had died many years before), and I remember seeing here face very vividly, as if the entire dream was real. Based on those experiences, I tried to draw her portrait, but try as I might, I failed miserably. I could just not access that imagery while awake. > I’m not sure why you think this is unlikely Now you got me doubting that as well :) I think that most of the misunderstanding stems from an unclear definition of what "forming visual images in ones head" means. I guess it means different things to different persons. For me, as referred to in the dream example, I cannot keep a sharp visual image in my head at will. But there is some vague access to certain visual memories and visual planning, so I would not call my self aphantasic. I agree that there is a great variation in how peoples minds work, that's what makes life so very interesting!
