You can use a lucid dream to leave your body?
When you are dreaming, whether or not you are lucid, you have
already left your body. You are, technically, astral projecting whenever you dream, but the dream acts as a kind of cocoon or bubble. It's not really protective in any way, rather, it's a small environment that you willed into existence from your imagination. Try willing it away or willing yourself to another location next time you're lucid.
