People who sleep flat on their stomach with their body outstretched feel like they're not in control of their life; those who sleep in the foetal position tend to worry unnecessarily; sleeping with your arms outstretched indicates you want more from life; and people who sleep straight like a log can seem bossy, according to a UK body language expert.
Robert Phipps says the body language we use when sleeping can tell us a lot about how we're feeling at the time, and it can affect the day ahead from the moment we wake up.
Foetal sleeping is the most common position, and people who sleep like this are returning to their comfort zone to de-stress themselves from the day's activities, he told the Daily Mail.
The higher the knees and lower the head the more internal comfort you give yourself.
"Foetal sleepers are conscientious, ordered and like things in their place, but they can over-think things and worry unnecessarily.''
