Earlier quoted context omitted.
Out of curiosity, how do you keep track of the spaces the characters move in if you can't visualise anything?
I'm not the original commenter here, but I don't understand your question. What does visualizing have to do with knowing where someone is?
How or where do you hold the knowing of the location of the fictional character? Look at that psychic phenomenon. Aphantasia seems like not knowing what psychic operations one does all the time, while someone who can visualize can consciously use these psychic operations.
