This was a long, but a super interesting read! I had heard about aphantasia, and I knew that I had some form of it. I can recall a flash of an image, but I can’t sustain anything. I’ve always had trouble recognizing faces unless I knew the person well. And I can’t recall my past well. I can recall photographs better, which I think is similar to the face recognition thing, where it’s an image that’s built up over repeated viewings.
Another interesting thing mentioned was the person who always had music playing in their head. I always have something playing in mine, even if it’s a snippet that’s on loop. I don’t know that I really could “hear” a complete song from start to finish, though.
