Back sleepers who pass out with their limbs extended in a starfish position are generally happy with their lives, are loyal friends and go out of their way to help others. You don’t strive to be the center of attention, but you don’t mind it either. If you sleep on your belly with your arms clutching your pillow or stretched out at your sides, otherwise known as a free-fall position, you are carefree and sociable…a free spirit. But you can also be nervous and overly sensitive to criticism, and you are trying to regain control over your life, even while you sleep.
