I can visualize nothing, but have excellent navigation skills. I can accurately remember the geospatial arrangement of cities and locations and routes I visited only once decades ago. That part of my brain has nothing to do with “seeing things”
do you have any experience of feeling like youve been at a particular place before. if you dont remember seeing it, do you just remember the arangement of landmarks like dots on a grid?
It’s an innate sense which most closely resembles proprioception (knowing where you arms/legs/etc are), or remembering where you put your keys. I suppose maybe it’s similar to “seeing” landmarks on a map (not necessarily a grid) but it’s simultaneously abstract while being very well defined in some intuitive sense: I know the Vatican is this way and the Colosseum is that way and the Spanish Steps are that way (and every other spot I cared to notice on the map), and no matter where in the city I walk and so long as I know which way I’m facing, I’ll 100% know the relative direction and distance of every other spot (as well as the pathing! Not just locations but also streets, etc). It’s actually hard for me to get lost.
