Anneliese Michel was a devout Catholic teenager living a normal life with her parents in Germany in the late 1960s. But then she began blacking out at school before exhibiting increasingly strange behaviors like routinely convulsing, hallucinating, eating spiders, and even drinking her own urine.
Michel claimed to be possessed by the devil, and her parents soon came to the same conclusion. They ultimately subjected her to 67 exorcisms, none of which improved her condition before she died of malnutrition at age 23 in 1976, weighing just 68 pounds.
Her story was so disturbing that it eventually inspired the 2005 horror film The Exorcism of Emily Rose.
