Last year in 2011 I got ready for bed like I normally would have, and I fell asleep like normal too. In the middle of the night there was this noise in my ears that sounded like when you put your hand over your ears. I opened my eyes and all of the sudden a hand pushed my face down into my pillow. Whatever it was wasn't trying to suffocate me because my head was turned to the side not facing the pillow, but it WAS for sure trying to make itself known. The noise in my ears immediately stopped and all was completely silent, then whatever it was whispered "F*** You". And and that point my eyes got really wide and I tried to sit up a little, but then the hands slammed me back down into the pillow with a great amount of force and it shouted this time "F*** YOU!". The noise in my ears came back louder than ever; I opened my mouth to try to yell, but the only noise that came out was an extremely soft noise. I sat almost in tears, because it was still holding me down. I couldn't move any part of me, I was completely paralyzed with fear.
A few minutes after it started, the hands and pressure and noise in my ears went away. I could move again. I jumped out of bed and quickly walked to my parents room. I tried to stay calm. I said, "Mom, Dad," I was really shaky sounding, "I think there is somebody in my room." They got up really fast and looked all around, there was nothing there. I knew they weren't going to find anyone.
Weeks and months passed and around February of 2012 the same thing happened to me again. This time I thought if I tried to act like I wasn't scared it would stop, so I smiled and tried to sit up. Whatever it was didn't like that. It slammed me down again, but I smiled still and tried to laugh to see if it would help at all.
Finally it stopped and I let out a sigh of relief. Now nothing like that has happened to me since, and if it does I'll know what to do.
