I was listening to a hypnosis tape on quitting smoking and I think I had an out of body experience.  I need help because no one I know can help me.  I was very relaxed and about to fall asleep and then all of a sudden I realized that I was sitting up in bed doing something on my computer...now I can't remember what I was looking at though.  All of a sudden, my arm (on my sleeping body), fell asleep and started to tingle.  Then I realized I was really asleep and then it was over.  When I looked on the tape, atleast 7 minutes had passed.  I was wide awake when I "woke up".  Is this an OBE or am I crazy?  Anyone with a similar experience or some insight that would help me...please write!  This is a new thing for me and I am wondering if it was real or a dream.
