What do they have?
They see visual symbols in their heads but nothing audible. They have no "inner voice" but still have thoughts, they're just visible
Ah! that makes so much sense, because I can't see anything visible in my head, even if I try to imagine something "visual" I only can get the name of it. Like when I think about seeing or visualizing an apple, all I can "see" is thinking of the word apple. Though I have been training for years now to visualize things. I can now visualize a short 1-2 seconds video. almost like watching a video on your phone. but I can't hold it for longer than 1-2 seconds. yet.
