OTW- great topic! Such scary stories. It is really interesting that it happens to troubled teenage girls. My sister had a really hard and troubled teen life.

I had to stay at home for awhile and she had taken my old room so I had to stay in hers. During that week I had the feeling that someone was on top of me. I know I was awake but I was too afraid to open my eyes. I could not move or scream. It would last for about 5 or 10 minutes until I forced myself to open my eyes. It was exactly like that "choking" effect. The only other person I have ever told was my sister because I thought people would think I was nuts if I told them. There was def. a presence in that room!
