The Dancing Plague of 1518

In the summer of 1518, a woman in France stepped into the street and began

to dance. She didn't stop for days. Soon, dozens,

then hundreds of people joined her. They weren't celebrating; they were screaming in pain and begging

for help, but their bodies refused to stop moving. They danced until

their feet bled and their hearts literally burst from exhaustion. To this day,

we don't fully understand what "demon" possessed them to dance themselves to death
