     Everyone has got two personalities-one is shown to the world and the other is 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, 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, your are a very open person. You normally trust people and you are easily

influenced by fashion or your new ideas. You don't like to upset people, so you never express your real feelings.

You are quite shy and you aren't very confident.

     If you sleep on your stomach, you are a rather secretive person. You worry a lot and always easily get upset,

you are very stubborn, but you aren't very ambitious (有野心的). You usually live for today not tomorrow. This

means you enjoy having a good time.

     If you sleep curled up, you are probably a very nervous person. You have a low opinion of yourself and so

you are often very 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 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. You always say what you think even if it annoys people.
