The hell if I know. Not a clue. It is my biggest question about them. I do think as I am typing and responding to you and all the other stuff I do but it is just there. I kind of equate it to having a filing cabinet. And in that filing cabinet are tons of folders and I just refer to each one of them even though I don’t see them or know what’s in them. Both aphantasia and anendophasia are relatively new in their research. Some of it I read makes sense a lot does not.
