During a dream, I suddenly became simultaneously conscious of my real body in bed; I don't know if it was a noise or what, but I was starting to wake up. I recognized this and thought, "Wait, that means I'm asleep... and that means that this is all a dream! No!" I tried to resist waking up and hold onto the dream, but I just couldn't do it. I woke up. Has this ever happened to any of you?
