Hello,
1. What you can expect is up to your beliefs.
You may end up in a dream or you may get out in the current reality. You may get into probable/alternate reality or anything what you are up to.
2. You can be really out of your body, because your live is outside of the body by default. You kinda projected into and got stuck somehow into the body once, now you believe that you are body, unaware of the 'other' larger reality.
