Apparently it doesn’t matter if you talk in your sleep – researchers can now figure you out just by looking at you. “The freefall, flat on the tummy with the hands at the sides of the head, is the most unusual position. Only 6.5 percent of people prefer it and they are usually brash and gregarious.” Strangely enough, this is pretty much the only way I ever fall asleep, and I had assumed it meant the opposite.
