I was just having a convo this very morning with Mr K (not the one on this forum) about the “area between sleep and waking.” I have studied lucid and prescient dreaming for a long time, but I always wondered about all those funny little ideas and images you start to get in your mind when you are just about to fall asleep. They’re so hard to describe sometimes, and yet you can derive a lot of insight, information, or whatever it is, from them!
