If someone you know kicks and punches you while they are sleeping, it may be because they have something called REM sleep behavior disorder or RBD, an extremely rare sleep disorder that affects an estimated 0.5% of adults worldwide.

Now researchers say they have identified some of the risk factors that contribute to someone getting RBD, which they believe can be a precursor to neurodegenerative diseases like Parkinson’s. Over half of people with RBD develop a neurodegenerative disease, according to the American Academy of Neurology.

When people without this disorder are in REM sleep (the short period of time when you actually dream), their muscles are usually in a state of paralysis (atonia), according to the Cleveland Clinic. But people with RBD move their body or limbs while dreaming. and they could be acting out what they are dreaming. People with RBD are in danger of harming sleep partners as they act out.
