Fetal Position
The most common sleep position (41% of people) correlates with sensitivity and introversion. People who sleep in fetal position tend to appear tough on the outside but are sensitive at their core. They take time to warm up to new people but form deep bonds.
The Starfish
Sleeping on your back with arms up correlates with being a good listener and not wanting to be the center of attention. Starfish sleepers tend to be loyal friends who avoid the spotlight but are always there when needed.
The Freefall
Stomach sleepers with arms around the pillow tend to be bold and sociable on the surface but can be thin-skinned and sensitive to criticism underneath. They often don't handle feedback well despite projecting confidence.
