Researchers say that sleep paralysis often occurs during periods of stress, irregular sleep schedules, or sleep deprivation. It’s also more common among people who sleep on their backs or have disrupted sleep cycles due to shift work or jet lag. Even though it feels frightening, doctors assure that it’s not dangerous and doesn’t cause lasting harm. However, recurring episodes can signal deeper sleep issues, like narcolepsy or anxiety-related disturbances.
Many cultures have tried to explain the phenomenon in spiritual or supernatural terms for centuries. Folklore from around the world describes “night demons” or “shadow visitors” pressing on a person’s chest — likely inspired by the realistic hallucinations that can accompany the paralysis. Today, scientists know that these visions are caused by a mix of half-awake dreaming and the brain’s fear response triggered by immobility.
Experts recommend improving sleep habits to reduce occurrences. Keeping a consistent sleep schedule, managing stress, and avoiding caffeine or heavy meals before bed can make a big difference. If episodes happen frequently, consulting a sleep specialist can help uncover possible underlying causes.
Though the experience can be deeply unsettling, understanding what’s happening to your body takes away much of the fear. Sleep paralysis reminds us how powerful — and mysterious — the human mind can be, blurring the line between dreams and reality in the quietest hours of the night.
