The way you sleep is quite telling, according to sleep experts. There are six basic sleep positions and each position says something about the sleeper. If you sleep curled up in the fetus position, you're described as tough on the outside and soft on the inside. If you sleep and look like a log, you are easy going. And if you're a starfish, with your arms up and out, you are likely to be a good friend, a good listener and always willing to help.
If you sleep in another position, there are more here with their descriptions. I apparently am the "yearner."
