Congratulations for trying to mimick an out of body experience. I, of course, have experienced it in real life.
I do not know if science is interested in the real deal, however, it came to me at two different times. 1) Extreme migraine suffering 2) Emotional distress
1) Migraine suffering that dibilitates you to bed rest without noise and light and on a migraine medicine and you are begging for sleep to excape the flashing lights that appear to you even with your eyes closed....really awful. But suddenly, I had relief....odd relief as I saw myself looking at me lying in the bed, motionless. I was shocked even in sleep and I recall trying to lift my arm to touch the apparition of me looking at me. But the lifeless body on the bed had no response. I stared in blank expession at the body on the bed. The body on the bed was exactly that. No life. The essence of the spirit had transformed itself in to the "out of Body" I don't know how long before it came back to the body. I remember thinking it was ok to come back, I am better now. My assumption of the transition was it was the only way to obtain relief from physical pain.
Secondly, I was experiencing emotional distress due to a temporary marital difficulty. I felt a different kind of pain. It hurt deeply and I sobbed uncontrollably. This has only happened once in my life. It was either out of body or an angel. Due to a disagreement, I was left alone and worried where my husband could be, is he alright...I would hear a siren and imagine the worst. Being some at fault, the guilt was seemingly overwhelming. I could not sleep, up and down....getting nauseua, feeling more than awful...finally I dozed...I felt the bed move and I thought, thank God, he is home safely. I remember not having the energy to discuss anything and that I just lay there still. The next morning, I awoke and rolled over to see my husband. He was not there.
The bed had an impression on it, it was unmade (his side) but on top of the bedspread was like a body impression. He had not been home. I was totally alone that night. But, I feel, my spirit, a spirit, came to comfort me. I was stunned in disbelief and discussed this with my sister the next day. I have had two other out of body experiences but never another one like this one. The other two were migraine related.
Good luck in your studies. I can't imagine magnetic imaging having the same effect as these but out of body does happen. Listen to those that have experienced it.
