Everyone has got two personalities(个性)—one shown to the world and the other secret and real. You don't show your secret personality when you are awake because you can control your behavior, but when you are asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you go to sleep in.

If you go to sleep on your back, you are a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don't like to upset people, so you never express your real feeling. You are quiet, shy and you aren’t very confident.

If you sleep on your stomach, you are a rather secretive person. You worry a lot and you are always easily upset. You're very stubborn(顽固的), but you aren’t very ambitious(有野心的). You usually live for today, not tomorrow. This means that you enjoy having a good time.

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

If you sleep on your side, you have usually got a well-balanced(通情达理的) personality. You know your strengths and weaknesses. You are usually careful. You have a confident personality. You sometimes feel anxious, but you don't often get depressed(沮丧的). You always say what you think even if it annoys people.
