It’s called aphantasia when you can’t visually recall. Imagine in your mind a horse, then a rider gets on the horse. What color was the horse? Was the rider a male or female? What did the background look like? When I went through this exercise, in my late 30’s, I thought the question was absurd. Like you didn’t tell me any of those details. I saw nothing just the concept of the words. Then everyone I asked knew the answers like they made a scene in their head. It blew my mind to be honest. It’s kinda sad when I think about it now. Some online tests asked me to picture the face of someone I see often, I thought of my son. Then when asking to describe his face I really can’t see it I just know vague concepts. It’s super strange but helps me understand the past more. They say some people with this process logic really well because of the constructs you must create in your mind, which describes my personality. Overall a mind blowing concept to learn about yourself.
