Wow. I didn’t know this, but I was actually able to observe this state on myself. When going to sleep, my mind is wandering. But at one point it drifts from real world thoughts to completely abstract concepts and wild imagination that sometimes makes no sense. It’s almost like a hallucination. What’s most interesting is that sometimes I am able to notice the transition to this state and consciously observe it. Usuall…
Same here. In periods of my life when I'm more into artistic creation (or even consumption), often quite vivid and elaborate images come to my head in the 10-15 minutes before going to sleep. That, or really rich and elaborate (original) music. Unfortunately, I don't have the skills to put them into paintings or compositions, or even to make a quick note of them so that I could remember them in the morning. But still, it's quite fun.
