astral projection and ufos

I have many experiences of leaving my body especially when I was a child. I was so frightened and had no way of explaining to anyone. It was horrible spending whole days even at Christmas sitting behind myself with the most awful tinnitus. When I was about ten my friends were jumping from a small garage roof onto mattresses it looked such fun so I tried my body jumped and I was still up there. I had to jump twice but I couldn't reconnect with myself. It was difficult getting home as I was walking behind myself. I seemed to be able to control my body somewhat but the buzzing noise made it difficult to communicate. I couldn't hear properly. Has anyone else had this experience? Please let me know.
