You probably haven't given much thought to your sleep position，but like your Spotify playlists or the clothes hanging in your closet，the way you spend those seven to nine hours each night can actually reveal a bit about who you are.
   The Fetal Position
   The fetal position gets its name from the shape of a baby in the womb.The fetal position is the most common position in the world.People who sleep in the fetal position tend towards worry and anxiety.They are often shy and sensitive.
   In the fetal position，a sleeper's body is essentially curled up into a ball as they lie on one side with legs and arms bent.This position is commonly assumed by adult sleepers.
   The Starfish Position
   When sleeping like a starfish，you lie on your back with arms up near the pillow and legs outstretched.Sleep scientist Idzikowski says starfish sleepers value friendship，and that while they prefer not to be the center of attention，people who sleep in his position are good listeners and quick to help others.If you have a starfish sleeper as a best friend you're in luck Star fish sleepers are great listeners and a source of comfort to others.
   The Log
For those who suffer from back pain，the log position could be helpful for you.While assuming a log position，a sleeper has both their arms and legs extended，so their body is straight like a log.Log sleepers are very trusting，a little naive，but are usually social and easy-going individuals.
   Idzikowski claims that preferring a log position suggests that a person is sociable and interacts with others easily.While these are attractive trails，he warns that this openness and willingness to trust could make them gullible.
   The Soldier Position
   In the soldier position，you lie as straight as a soldier stands.The legs are not bent，and your arms lice straight along the sides of your body.
   Soldier sleepers are quiet and reserved，but also hold high standards.Soldier sleepers do not like to make a big deal out of things.They are the strong silent type.Sleeping like a soldier can lead to a bad night's sleep.Try using a pillow to support the natural curve of your back.
