Ever since I started lucid dreaming (the hobby), I have been becoming more and more aware of my mental state. A couple days ago during a super boring movie (Not essential to the course, the teacher felt like being "nice"), I closed my eyes and started to fall asleep.

Oddly enough, earlier that day I was thinking about if I dreamed during micro-sleeps such as this.

So anyways, I noticed was seeing through my eyelids, I still felt myself leaning on my folded arms, but I saw the rest of the room, and noted I was on a different table. I was a little startled and opened my eyes and sat up, awake. I did a nose and memory RC, both succeeded. I tried to return to this state again, and I did.

I got into this blurry, see-through-eyelids state, and tried to affect the world at all. Even attempting to focus on something, never mind reality checking, would thrust me out of this state. It happened all 3 times, then the period ended, and I couldn't stop thinking about it for a while.

Has anyone ever been in this state? Is it a Pre-REM dream maybe? Could I control it somehow? I need answers!
