so dig this: most people can clearly and in detail "see" things inside their heads. like if they want to pretend to be on a beach or stage or in a sports car, they can just close their eyes and visualize that like they're in a 3d space in their heads.   


if this comes as a surprise to you, I'm sorry, I really am. You might be Aphantasiac, the wikipedia article on it is a good primer.  


I just wanted to see if anyone else has an overlap of BPD and aphantasia.
