What does it mean when you can see yourself sleeping?

trust me it happens to everyone every time they go to sleep its called astral projection when your ghost leaves your body i do it on purpose just to fly, most people debunk it as "dreaming" but its astral projection & on occasions you dont realize your doing it the best part is pulling your friends out of their bodies but i think you saw yourself because one you astral projected your physical body must've heard a thump/bang or loud noise to wake your astral body hope this helps :)
