What position do you sleep in?

"Scientists believe the position in which a person goes to sleep provides an important clue about the kind of person they are."
I really enjoy the different position names:

The Foetus
Log
The yearner
Soldier
Freefall
Starfish
Farting Buffalo

Ok.. I'm lying about the farting buffalo.
Well I know this whole thing is a little retarded but I think I may be:

The yearner (13%): People who sleep on their side with both arms out in front are said to have an open nature, but can be suspicious, cynical. They are slow to make up their minds, but once they have taken a decision, they are unlikely ever to change it.

I wake up in different positions all the time. Does this mean I have split personalities? Must be.
