     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 your

behaviour, but when you're 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're 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

feelings. You're quite shy and you aren't very confident.

you're always easily upset.You're very stubborn(顽固的),but you aren't very ambitious.You usually live

for today not for tomorrow.This means that you enjoy having a good time.

     If you sleep curled up(卷曲),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. 

     If you sleep on your side,you have usually got a well-balanced personality. You know your strengths
