What happens if you AP and then do nothing?

When I lucid dream I sometimes just sit down, close my eyes, and try to meditate. Usually this leads to the mind getting "bored" and ends in a loss of consciousness or a new, different, more vivid dream. I'm wondering has anyone tried this in the astral? Is it even possible to "close your eyes" while astral projecting? If you just sit there, will anything change? Do you go back to your body? Many questions!
