Hey. I think I can help you relax. When my anxiety started, one of my first symptoms was actually sleep paralysis. I'm not going to lie... It was scary the first time it happened. You feel possessed because you can't move. This is only because when you're in deep sleep (REM) your body is paralyzed and you dream. All sleep paralysis is, is your brain waking up before your body does. It's weird but I found out that when I do get the sleep paralysis, I just close my eyes and I'm INSTANTLY asleep again. The hallucinations are actually just dreams. Dreaming while awake! It's nothing to be frightened about.
