Lama Ole’s answer:
That is a good state. It is good if one can leave the body; this is a sign of good karma and previous meditation. It means that you have little attachment to your body. It will be easier for you to do something for others, and dying will be easy, too. You should mix this wisdom with compassion so that you consciously do what benefits beings.
Hannah, my wife, often experienced this phenomenon of seeing herself from above. When she was a child, she used to see herself from a corner of the room. I have mostly experienced these states while on LSD or during accidents. Once while climbing, I fell ten meters down because the foothold I had put all my trust in came loose. There I was outside of my body. I saw my body spin around and knew that if all went well, I would continue to live, and if not I would go somewhere else.
