God I had the freakiest nightmare last night. I really never have nightmares and if I ever do I usually become lucid before it gets too bad, but that didn't happen this time. The last time I had a dream as scary as this was about two years ago and was interrupted by a sleep paralysis episode where I hallucinated something very similar to this dream. Anyways, I've copied it here from my dream journal:

Entry 010
I'm in Dr. Clark's room. We have some huge essay to write, it's due in 30 minutes, but I'm so tired. I lay my head down on my desk and fall asleep.

I'm in my bed, except I realized later that it was on the wrong side of the room and exact to my old bed back home. I'm half-asleep, my body is already paralyzed and my mind is mostly unconscious. As I'm lying there, about to enter a deep sleep, I feel something on my back. It feels like a hand. For a minute I don't feel particularly worried about this. The hand is running over my back, slipping lower until it runs over my ass. I feel uncomfortable. Then I can feel nails digging into me. I realize there is no hand, but the touch persists. I realize the hand belongs to some kind of demon, and that its intention is to murder me. My body is still paralyzed. I try screaming, but all that comes out of my throat is a strangled grunt. It's not loud enough for anyone to hear. I know that I have to stand up and get out of here. I try to stand, but I can't. I fall to my knees and drag myself to the door. Along the way I see something out of the corner of my eye. It's a little man, about as wide and tall as a bowling pin, dressed in clothes like Charlie Chaplin with white pasty skin, frizzy black hair and huge, staring, yellow eyes. I open the door and drag myself to the hall. I try screaming more, but I'm still not able. I think I see my mom on the couch, but it's dark. I get to the couch, someone's there. I'm safe. I relax, fall asleep by the couch.

I wake up. I'm in bed. Something is touching me. Repeat of the last dream, but as I reach my door this time I think "My bed is on the other wall. Didn't I just have this dream?" and I realize I'm dreaming. My dream self, however, is still panicking. It's screaming at me to get the hell out of the room. The will of my dream self overpowers my lucid self and I fling the door open. There's a blinding white light.

I open my eyes. I'm screaming. My mom is in the doorway.
Also, this is the first time I've had like 3 layers of dreaming. It was a dream inside a dream inside a dream. Creepy as hell. I haven't woken up screaming since I was a kid, either. Just wondering what the hell would provoke something like this. Demons (or malignant entities, whatever you want to call it) seem to be a reoccurring theme in bad nightmares of mine, too. Any thoughts?
