Everyone has got two personalities—the one that is shown to the world and the other that i

s secret and real. You don't show your secret personality when you're awake because you can control your behavior, but when you're asleep, your sleeping position shows the real you.

If you sleep curled up, you are probably a very nervous person. You have a low opinion of yourself and so you're often defensive. You're shy and you don't normally like meeting people. You prefer to be on your own. You're easily hurt.
