When it comes to sleeping positions personality assessment, if you sleep like a log–literally, with your body straight as can be and your arms straight at your sides, like a soldier–then you may be reserved, stubborn, and a bit bossy. You like to be in charge and you’re not very flexible and loose. If you sleep on your side with your arms outstretched, you are known as a yearner. This common sleep style is preferred by people who are live to chase to their dreams; your arms are outstretched because you are reaching for something. On the flip side, people who have dreams about being chased might also gravitate toward this position, because you are trying to get away from someone or something.
