Interesting, how do you experience spatial memories? Is it somehow encoded verbally, or via somatosensation? Or does it feel completely subconscious, like a Pavlovian reaction? Or something else?

I am bad at visualizing things from what I can subjectively tell, but as far as memory is concerned it's mainly the spatial memory tests where I perform poorly. So it's hard for me to imagine what recalling spatial memories is like, besides the assumption that people can probably visualize them.

It's kind of (but not exactly) like proprioception. Close your eyes and hold your hand out. Even without visualing (because we can't...), you know "where" it is. It feels a lot like that. I just have a good sense of where things are relative to me and each other.
