        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

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