When I was beginning to use AI for everything, as most of us had, I would start dreaming that wall of text that had a personality sat between me and reality. For several nights I would dream this way with the wall becoming translucent and displaying text but the "real" actions (other people, scenes) was happening on the other side of the wall. I've dreamed in videogames as well. I'm not sure if I was getting any learning done, but I'm pretty sure my brain was exercising modes of thought that would push knowledge from "system 2" down into "system 1."
