it isnt uncommon to see other people when astral travelling, and if you saw the ceiling then im guessing you were, if things become confusing you're possibly slipping back into lucid, though im not sure how to stop this, try concentrating on your hands for a while. if you want to know if your obeing i suggest next time you see if you can see your body, although seeing your body might send you back. i dont know whether this helps or not but good luck anyways, kudos to you. xxxxx
