Everyone has got two personalities — the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control yourself, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you go to sleep.

If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by new ideas. You don’t like to make people unhappy, so you never express your real feelings. You’re quite shy and you aren’t very confident.

If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you’re always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not for tomorrow.

If you sleep on curled up (蜷缩), you are probably a very nervous person. You have a low opinion of yourself and often protect yourself from being hurt, so you are very defensive. You’re shy and you don’t usually like meeting people. You like to be on your own.

If you sleep on your side, you have usually got a well-balanced personality. You know your strengths and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel worried, but you don’t often get unhappy. You always say what you think, even if it makes people angry.
