Can you help me fight my dreams?

I never sleep well.
I wish I could, I want to go to sleep at a proper time and wake up feeling refreshed, not sleepier than before.
I just hate what happens when I try to sleep.
This is what happens:
I lay down in bed, extremely tired.
I close my eyes, and then, I'm not sure what it is, but I fall into this sort of half-sleep. I literally fall into it, one second I'm awake and the next I'm in this fuzzy, grey and mauve state. Except I don't even know I'm asleep yet. I think my eyes are open, but just barely, I think I'm moving in my bed, but I'm not; I'm immobilized, I can't move at all. I see my room, I think I'm awake in bed, I'm convinced everything is just so strange because I'm stoned. Except it's not like being stoned, nowhere near. So anyways, I'm in bed, I see the opposite wall, everything's blurry and growing in proportion, the walls get farther away, and closer very quickly. This all doesn't seem so bad. That's because it isn't the bad part. My door opens, I see my mother, I think she's coming to check on me, but she either stands in the doorway or runs up to me quickly, leans over my bed and falls through me, the mattress, and straight through the floor. Like a ghost, I guess? Then enormous pressure comes and sits on my knees and elbows, like someone's pinning me down. Through my half-opened eyes (remember I'm dreaming that my eyes are open) I look down on the end of the bed and see little shadows, or like last night, a frightening flickering man, blue like a corpse. Then, whatever/whoever it is starts ripping off my skin. Literally ripping it off. I can't feel it, but I know it's happening, I see it happening. I can't scream out, and again I think I'm moving but realize I haven't moved an inch, I can't. I look back to my mom to help me and see her in the doorway again and her eyes are black and blurry and she's much taller than usual and she's flickering, like when you watch a VHS movie and the picture gets wavy when you first turn it on. She just stands there and watches. I'm not breathing anymore, but I'm not dead, I'm not even allowed to die. I can't even describe how scared I am. I can't move, I can't scream, I can't even tell myself to wake up because I don't even know I'm asleep. And then, when all my flesh is gone, my mom (better yet, mom-creature) shuts my door, loudly, and I fall again. I feel a incredible jolt, as if I was thrown down onto my bed from at the ceiling. Now I know I had been asleep...rather, that awful half-sleep, and I can't shake the images from my head. So I lie in bed with my back to the door, because I don't want to see my "mother's" blurry black eyes. Eventually I fall asleep, really asleep, but I'm too wary to ever sleep well, it's always disjointed and stressful.

So that's what happens when I try and sleep, and I don't know why.
I think I'd feel better if I knew other people experienced something like this too. This isn't a one time thing. It's nightly, but it's much more frightening at my mother's house, at my dad it's just the surreal awareness and the shifting proportions of my room.

Does this happen to you? Or do you know what it is? I really would like to sleep.

And yeah, if it happens every night you'd think I'd remember that it happens and realize it's a dream, but I don't. Every time I'm convinced it's real until it's over.
