Perhaps sleep deprivation is the answer, but it really scares me. I have been known to claw up my face and arms and it's really frightening. I mean if I were doing this to myself while actually asleep, I may not be as worried, but I feel like I'm crazy when this happens while awake.
I'll admit to having random small hallucination throughout my day. i'll see a flash of something that couldn't possibly be real, and that then it won't be there, but it's not like my dreams. On one occasion i dreamed that there were half-rotted bodies were crawling out of my bathroom trying to get me. I woke up and I could see them through my open door...I was so real that I just started freaking out and screaming and then at some point they vanished--though I can never really differentiate when the creatures go away. They actually go hide somewhere and then I spend hours looing for them before I can go back to sleep. Am i crazy?
