Become conscious before the end of the REM cycle, when body is still relaxed
Occurs shortly before falling asleep
Normally, when you fall asleep, your awareness decreases
In SP, you remain aware and notice you cannot move/speak
Relax your body into
Don't fight it forcefully as this will create panic and increase the chance of negative hallucinations.
Wiggle your toes, fingers, and eyebrows. Rapidly blink or move your eyes around.
Go with the flow and recognize that you are in a sleep paralysis episode.
During normal REM sleep, the body secretes hormones that induce muscle atonia, which prevents someone from acting out their dreams.
The hormones fail to wear off at the end of the sleep cycle in SP.
region of the brain responsible for fear
In SP, our eyes are often open while we're still in the dream state.
Opposite of SP.

Descriptions of sleep paralysis in works of fiction
Herman Melville's Moby Dick
Accounts of F. Scott Fitzgerald and Ernest Hemingway
Henry Fuseli's paintings
St Lucia: souls of unbaptised children who crawl on to the sleeper's chest and throttle them.
Europe (Middle Ages): nocturnal witch visits
Newfoundland: "Old Hag"
Japanese: "Kanashibari" (bound or fastened in metal)
China & Taiwan: "Meng yan" ghost oppression
Thailand: "Phi um" (enveloping ghost)
Hawaii: "Hauka'I po" (night marchers)
a peculiar case of SUNDS
117 healthy Hmong immigrants suddenly died in their sleep
Had barely been on American soil for a few months
Median age of death: 33
Death rate = top 5 natural causes of death for other American men of same age group
No obvious cause of death; none were sick
Were only united by shared culture
the power of the nocebo
Doctors have found that patients made to feel anxious need larger amounts of opiates after surgery than other people.
Pretending to expose people who say they are sensitive to electromagnetic radiation to cell phone signals can give them debilitating headaches.
Chinese Americans die younger if they were born in a year that was astrologically linked to poor health.
Similar effects were not found in the white populations around them.
How much sooner one died depended on
the person's "strength of commitment to
traditional Chinese culture."
