During my college year I had three out of body experiences. They happened because I prepared myself for it.I layed on my bed facing up, closed my eyes and meditated about my energy self leaving my physical body.The room had to be qiuet and my body was completely free from any little obstruction. Listened very attentivelly to my breathing as I inhaled and exhaled.There was a moment in time when all of a sudden I became weightless and was floating close to the ceiling. I do not have any explanation, but I appeared suddenly floating closed to the ceiling in the hall way outside my dormitory room. I felt a surge of air current overtakened me and I floated along with its flow toward the end of the hallway in which I flew out and was looking down the stair ways to first floor.I saw my buddies; four of them and I heared what they said. One of them slammed the door which woke me up.I went out to see them and they were still there just as I saw them in my OBE. I declined to their invitation.
