In a nutshell
Some people punch, kick, or call out in sleep in ways that match a dream. Recurrent acting out of dreams may indicate REM sleep behavior disorder and is not simply especially vivid dreaming.
Why does it happen?
Normal inhibition of skeletal muscles during REM sleep is partly lost. As a result, motor dream impulses can pass into actual movements. Symptoms and sleep recordings are assessed together for diagnosis because other sleep disorders can cause similar movements.
Frequency
REM sleep behavior disorder is much rarer than occasional harmless sleep movements. Its frequency depends, among other things, on age and the population studied.
Frequency is a qualitative description, not your individual probability.
Is it normal?
A sleep disorder that needs treatment, not a special ability.
When to seek advice
Have recurrent punching or kicking during sleep medically assessed, especially with injuries; until then keep hard or sharp objects out of the sleeping area.
