The enigma of nocturnal immobility: when the body refuses to obey

Contrary to what one might think, sleep paralysis is a common and harmless condition. Nevertheless, it remains a disconcerting experience when it occurs unexpectedly. This particular situation most often manifests as you are falling asleep or waking up: you are alert, your eyes may even be open, but your body no longer obeys. Motionless, unable to speak or react, you feel trapped inside your own body. This disconnect between an awake mind and a paralyzed body often causes intense anxiety.

Adding to the strangeness of the moment, some characters exhibit characteristics of sensory hallucinations. Menacing shadows that seem to be spying on you, incomprehensible whispers… All these details give this episode the feel of a nightmarish scene experienced with eyes wide open.

Where does this curious phenomenon come from?

Rest assured: you’re not losing your mind, and no supernatural presence is involved ( even if some urban legends still suggest otherwise  !). Sleep paralysis is explained by perfectly normal bodily mechanisms. During REM sleep—the phase in which we dream—our brain temporarily inhibits our muscles to prevent us from acting out our dreams. During an episode of paralysis, the mind awakens while the body remains under the influence of this inhibition. The result: you are awake… in a sleeping body.
