Is is normal to "wake up" to this feeling?
Every once in a while, shortly after I fall asleep, I will "wake up" and be aware, but not totally awake. I hear this intense buzzing sound, and when I try to move around, I can feel a weird separation from my body, as if there is a separate body of mine moving instead of my physical one. I can sometimes make myself do this, but I forget to/can't breathe normally, so I get scared and stop.
I've tried to look up what it could possibly be, and found something familiar called "astral projection" but honestly, that sounds like total crap to me, I'm an adult and an atheist who doesn't believe in the supernatural and just wants an explanation and maybe an inkling that what I'm going through is normal.
Anyone?
