"Tell me how you sleep...and I'll tell you what kind of person you are!"

Fetal position (41%)

The most common postures, especially among women (51%). Corresponds to people whose outward appearance hides an extremely strong sensitivity. They are shy at first contact, becoming more relaxed and opened with time.

Trunk (15%)

Sideways, with the arms close to the body. Those who sleep in the "trunk" position are usually sociable and friendly persons, also very popular. They can trust too much, becoming naive.

The "hunchback" (13%)

Similar to the trunk but with arms in front of the body. People who sleep in this position tend to possess an open personality, although they may become suspicious and cynical. They take their time to make a decision, but when they take it, they tend to be irreducible.

Soldier's position (8%)

On his back, with arms and legs stretched over the body. Typical calm people, reserved and demanding, both with the others and with itself.

Freefall (7%)

Face down with hands under the pillow, head to one side. On the outside, these people may seem outgoing and boisterous; in fact, their spirits are nervous and very sensitive to criticism.

Star-fish (5%)

On his back with arms under the pillow and legs outstretched to the sides. In this position seem to match good listeners who make friends very easily, but they hate being the center of attention.

According to research by the British author, the freefall position benefits the digestion, while those who prefer to sleep as "Star-fish" " or "Soldier" are more likely to snore and have disturbances during sleep. Also according to the survey Idzikowski, most people sleep with one arm or leg outside the covers. One in ten people cover themselves completely with the bed clothes.
