The Hmong believe in dab tsog — an evil spirit that sits on the sleeper's chest and suffocates them. Between 1977–1988, over 117 apparently healthy Hmong men died in their sleep after resettling in the US. Wes Craven read about these cases and created A Nightmare on Elm Street.
Dab tsog — a direct parallel to the Slavic Mora, Japanese Kanashibari, and the Old Hag. But with a terrifying twist: SUNDS (Sudden Unexplained Nocturnal Death Syndrome) killed 117+ healthy Hmong men in their sleep (1977–1988). Median age: 33. 98% of deaths between 10 PM and 6 AM.
Researcher Shelley Adler (2011) argued this was a nocebo effect — the power of belief in dab tsog, combined with war trauma, loss of homeland, inability to perform protective rituals, and rapid acculturation created fatal psychosomatic stress. Wes Craven read about these deaths in the LA Times in 1981 — and created Freddy Krueger.

Did you know belief in a nightmare-demon can be lethal? Hmong 'dab tsog' combined with extreme stress may have caused actual deaths — the nocebo effect in its most extreme form.
Did you know the men began to fear sleep itself? They set alarms to wake up regularly, some tried not to sleep at all — paradoxically increasing the risk of sleep deprivation and paralysis.
