Sleep position gives personality clue. (via Belicove.com) Many people will claim that they sleep in different positions at different periods. So if one sleeps in all positions, how can it really tell your personality? And my own question, does sleeping position correlate with the sleep cycle? It's probably answered somewhere, but I'm not well versed in sleep research. Me? I fall asleep in the fetus position. I wake up in the soldier position. And I like covering up my entire body with the blanket. Including my head.
