Soldier position - These sleepers lie on their backs with arms down and kept close to the body. This 8% study is said to be reserved, quiet, without fuss, and hold themselves and others to a high standard. Soldier sleepers have a higher likelihood for snoring due to the flat-back position, which may not cause them to wake up often but may result in a less restful night's sleep.
Starfish position - Sleepers who lie on their backs with arms up near their head or the pillow account for 5% of participants. These people are good listeners, helpful, and are uncomfortable being the center of attention. People who sleep in starfish position are more likely to snore and to suffer from a poor night's sleep more often.
Well I am typically in the soldier position but at times will tuck up my arms under my pillows if I just can't fall asleep.
Oh and I don't believe the snoring part AT ALL no matter what anyone says.
