Possible explanation for alien abduction from bed?

Well last night, I feel into a bit of a deep sleep, and for some reason I woke up at about 1 AM, two hours after I went to bed. The thing is that when I woke up, I was on back, with my head ****** a little to the side, and my eyelids were only half open. I also noticed I couldn't move since I wanted to lift my hand to scratch my head. Immediately afterward, I noticed two dark figures (looked like short people with cloaks) on either side of my bed. I started panicking, thinking, "Oh hell no, not again!" (I'll explain in a minute), but then I regained control of my body after about 5 seconds, and I realized that one of the figures was just my lowered eyelids creating an illusion, and the other was my dark blue bunched-up cover off to the side. I considered sleeping with my light on for the rest of the night, but I figured that would just be too paranoid. Anyway, I did have an experience a bit like this when I was about 3 years old, so I'm not putting all this on here to discredit the abduction fanatics. On that night, I woke up to see 4 or 5 greys at the foot of my bed (I could see them clearly because they far enough away and were illuminated by my orange night light. 2 were the plain naked types the size of 10 year olds, and the others were stumpy and wearing big cloaks that concealed their faces). I didn't know what they were at first, I just figured they were some kind of people I'd never seen before, although I had no idea what the hell they were doing in my house. I don't remember being "frozen," all I remember seeing was them standing there looking at me. One of the stumpy ones was gazing into my parents' room, which was right next to mine. Too bad I couldn't see their feet, I heard they have hoofs. Anyone else on here have an experience like the one I had last night? Also, do you remember if you were you dreaming just before you woke up?
