Ok I am going to tell you something that happened to my sister when we had a sleep over one night.At the time I was 14 and my sister was 12 or 11.But this is what happened.Ok it was about 11 or 12 at night and my friend,my sister, and I were all goofing around.Well we decided to go to sleep. We all laid down.(At this time me and my sister shared a room).Well anyway we all laid down and we were talking with the lights already out.Then we all said good-night to each other and closed our eyes.All of a sudden at the same time we all arose to the creepy sound of someone tapping their fingernail on the window as if trying to get our attention.We were all too scared to get up and look out the window to see who it was.Well we all stayed put.Then we heard it again and we all were putting our heads under the covers.Well my sister had her feet curled up under her and all of a sudden she says in a quivery voice 'Steph,something just pulled on my foot and I am NOT joking.' Well I have never had anything happen to me like that but I do believe in that stuff.So I took her seriously and she told me to turn the light on.Well at first I was hesitant because of what just happened.But then I got up enough guts because I didn't want it to happen to my sister again.So I ran for the light switch and I turned it on.From then on throughout the night we slept with the light on. The thing is that my friend that I had staying the night was 16 at the time and she was more frieghtened than anyone. Well the next morning we told my mom what had happened because she believed that stuff because some of it had happened to one of her uncles. Well anyway I told her that my sister screamed so loud that would have probably heard it all the way outside.So then what she said next really freaked us out.She said that everything was silent all night long.She said she never heard anything and that was because the walls in our mobile home were as thin as paper! So my mom went and cleansed the room and till this day nothing has happened that weird. So if this happens to any of you try cleansing your house or room or whatever you think is possessed. If it doesn't work then God be with you.
