Scientists found that the way you sleep may say something about what kind of person you are. The findings came from a study of around 1,000 people. Here are the six common sleeping positions (姿勢) that were studied.

 Fetus:This is the most common sleeping position. People who sleep in this position are thought to be strong on the outside but soft on the inside. They are shy but warm up quickly. Log:People who sleep on their side with both arms down are social and easygoing (隨和的). They are trusting of strangers and may be easily tricked. Yearner:Yearners are people who sleep on their side with both arms out in front. They are slow to make up their minds, but once they have made a decision, they don’t want to change it. Soldier:In this position, people lie on their back with arms down at their sides. These sleepers are quiet and don’t like to share their feelings or thoughts. Freefall:These people lie on their stomach with arms up. They are friendly, and they enjoy meeting and talking to people. However, they care too much about what others think of them. Starfish:People who sleep on their backs with arms up make good friends because they are helpful and always ready to listen to others. However, they hate being the center of attention.
