This has happened a few times so no big deal but the memory of it stays which is unusual for me. I get this feeling of 'leaving' that I have to resist because I know I would die if I gave in. Like I'm being pulled out of my body through my head. There's a noise that I can't describe that happens. I know people do experience strange sleep disturbances and wondered if anyone else had the same one? Or make me feel less disturbed by sharing their sleep weirdness?
