Note: I live in a fairly new house that has had no former residents so I really don't know why this happened.
One summer night about 2 years ago I had a friend spending the night. It was about 11:30 PM and we were sitting up in bed talking. Suddenly a white shape arched over the foot of the bed. It went too fast for us to really make out what it was. I, who really didn't belive in that sort of thing, thought I was probably seeing things. But my friend gasped and jumped, so I asked her if she had seen it as well. She said she had and I began to get scared. We tried to figure out what it was, but the door to my room was closed and the shades were drawn. Finally I built up my courage and looked over the foot of the bed. On the floor was my white gorilla stuffed animal which had been on the other side of the room before it happened.
About a year later I was sitting on the floor at the foot of my bed lighting a candle. Suddenly I saw something fly over my head out of the corner of my eye. I looked over to where it had landed and saw my small, gray stuffed elephant on the ground. It had been sitting on the windowsill before. Since I was in the room alone at the time I freaked out and ran downstairs as fast as I could.
