I couldn't remember what happened!

I was at my friend Debbie's house for her birthday party and we were all downstairs in her basement. I was on her couch, she was on the small mattress, and our two other friends were on the big mattress. They were all talking about boys and junk like that, I never really speak up in conversations with more than one person talking. So I was just siting there when all the sudden I get the urge to lay down, and so I did. From then on I have no idea what happened, but my friends told me what they saw and heard. Apparently I started to cry and scream and say I hate you all. I was under a blanket and they tried to rip it off of me to see if I was ok. My friend Haley said I was holding onto that blanket with the strength of about 3 guys, and they couldn't pull it off. Debbie told me she was crying and kept asking me to stop it. After about 3 minuets I "woke up" I guess and did'nt remember anything that had happened. All of them thought I had just been doing it for a laugh but after I kept telling them that I did'nt remember anything Debbie said "Oh my God, you were possessed." I said "thank you finnaly a believer."

It really has'nt.
