1. In the prone position, sleeper lies face down on the stomach with arms extended and bent, usually framed above the head. People who regularly sleep in the prone position tend to have strong compulsive tendencies and stubbornness in their personalities and are persistent and goal-oriented.
2. The royal position is the geometric opposite of the prone. The royal sleeper lies supine, fully on the back, with arms slightly akimbo at the sides. It’s an open, vulnerable and expansive position, and these people display self-confidence and self-involvement. Workaholic businessmen and entrepreneurs often prefer this position.
3. The most common position, the semi-fetal, has sleepers lying on their sides with knees slightly bent, one arm outstretched above the head, the other resting comfortably on the opposing upper arm to cradle the head. Conciliatory, compromising, non-threatening, non-shakers; sleep experts claim this to be the optimal sleep posture position.
4. The full-fetal is the characteristic womb position. Sleepers lie curled on their sides, with knees pulled all the way up, heads bent forward. Usually a pillow or blanket mass is centered at the stomach. These people are highly emotional, sensitive, artistic, and have intense one-on-one relationships. Oddly, it’s found that women who sleep in this position normally have heightened capacity for multiple orgasms.
