What others have found interesting in the past is how I conceptualize spaces around me, especially when imagining things like my DnD campaign that I run. I don't see things in my head visually, but more have a general special sense of them. I don't need to visualize my foot or my hand to know where it is. I don't need to visualize the wall of my room that I'm very familiar with; even with my eyes closed I know my relative position in the space and can find the light switch in the dark, or the fan. It's the same for my spacial reasoning. I can navigate the world perfectly fine, or conceptualize a fictional DnD battle, not visually, but more like through touch, though that's not exactly the sensation. I cannot rotate the proverbial cube in my mind, but I can conceive of what another face might feel like, and, if it's not too TMI, I have a very good mental map of my fiancée's body, and could draw her accurately, even if I can't see her.
