I think this is an interesting study, what does your sleeping position say about you? Personally, I'm the "soldier". Not quite sure if I fit the description, but it's still interesting.
The Soldier
Position: Lying on your back with both arms at your sides.
Personality: Soldier sleepers are generally quiet and reserved. They don’t like to make a big deal out of things, and they set very high standards for themselves and others.
Health Benefit: Research shows that sleeping on your back may lead to snoring, difficulty breathing, and an overall bad night’s sleep. Is your snoring keeping someone awake at night? Try flipping over—you’ll both wake up more refreshed.
