But what does your sleeping position say about your personality? Surprisingly, quite a lot! With thanks to Science of the People, let's look at a few of the most common examples:

The fetal position is when you curl your knees in toward your chest like you’re tucked into a safe little ball.

In a study conducted by Chris Idzikowski, director of the UK’s Sleep Assessment and Advisory Service, 41 percent of the sleeping participants adopted this position. In fact, double the amount of women slept in the fetal position compared to men in this experiment. Those who find comfort in this natural position can be described as having a hard shell: tough on the outside, but a huge softy on the inside. They typically are shy when you first meet them, then tend to open up and relax quickly.

The Log: Fifteen percent of people seem to find passing out like a log (lying on their side with their arms by their side) as the best way to catch some precious z’s. Does this boring, stiff sleeping position mean the sleeper is boring too? No! In fact, the opposite is true. People who sleep like a log are known as social butterflies. Although they are friendly, carefree, and popular, these social, trusting people are known for being gullible.

The Yearner: As if reaching out for something, the yearner is the position where you sleep on your side, but have your arms stretched out in front of you. People who sleep like this are a little complicated: they are open-minded, yet cynical; slow and suspicious when making a decision, but stick to it once their minds are made up.

The Soldier: Exactly as it sounds, the soldier position is where you sleep on your back with your arms by your sides. Only eight percent of sleepers claim to get the most sleep this way. Those who find themselves sleeping this way typically are quiet, reserved and hold both themselves and other people to high standards and strict moral codes.

The Freefaller: Having trouble imagining this one? It’s where you’re lying on your stomach with your arms wrapped around your pillow and head turned to the side. Sleeping on your stomach is something many people find uncomfortable, but those who enjoy this position wouldn’t have it any other way. Freefalling sleepers are bold and sociable on the outside, but typically don’t have the thick skin to deal with criticism or absurd situations.
