The Top Ten Most Bizarre Cases of Mass Hysteria

1 The Dancing Plague of 1518

Hundreds of years ago in July, in the year 1518, a strange mania occurred in the city of Strasbourg. Numerous villagers became compelled to dance non-stop, seemingly for no reason, until their bloodied feet could support them no more. All of this began when a woman, Frau Troffea, began to dance fervently in the street, which lasted somewhere between four to six days. She seemed unable to stop, and kept dancing until she collapsed from exhaustion. After resting, she resumed the activity and continued this way for days, and within a week, 34 other people had joined. By the end of the month, there were already around of 400 people dancing. A number of them died from heart attack, stroke, or exhaustion, and eventually, the mania began to fade. It is unknown why these people danced to their deaths, nor is it clear that they were dancing willfully. - Misfire

2 Meowing and Biting Nuns

It all started in a large convent in France, when one nun began to meow like a cat. Soon, others joined in, and eventually every nun in the convent was meowing. All the nuns would meow together for hours at a time, leaving the surrounding community astonished. They all continued until soldiers threatened them into getting whipped or beaten.
A similar case occurred in Germany during the 15th century. A nun began to bite her companions, and it wasn’t too long before other sisters were biting one another as well. The behavior spread through other convents in Germany, into Holland and as far as Italy, and eventually, the biting came to an end, due to the nuns’ exhaustion. - Misfire

3 Tanganyika Laughter Epidemic

The laughter epidemic began on January 30, 1962, at a mission-run boarding school for girls in Kashasha, when three girls started to giggle. Their laughter would last anywhere from a minute or two to several hours. Soon, other girls were doing the same thing. No one could concentrate on their schoolwork, and restraining the laughing students proved ineffective. Weeks later, more than half of the school’s middle and high school students began to laugh uncontrollably as well. The school was forced to close down on March 18, 1962.
They reopened the school two months later, only to be closed again as the laughing plague immediately restarted right after they reopened it. It spread to other schools and lasted somewhere between six and 18 months. - Misfire

4 Day-care Sex-abuse Hysteria

Day-care sex-abuse hysteria was a moral panic that occurred primarily in the 80s and early 90s featuring charges against day-care providers of several forms of child abuse, including Satanic ritual abuse. It all began when a mother accused Ray Buckey, a worker at a preschool near Los Angeles, of raping her child. When the parents asked their children about acts like sodomy and oral sex, because of being asked to do so by the police, more accusations followed. Ray Buckey’s mother and the owner of the school, Peggy McMartin, along with other teachers were eventually charged with 208 counts of child molestation. As time passed by, the accusations got wilder. The children said they’d participated in Satanic rituals, being forced to drink blood and had witnessed a baby being sacrificed in a church. The trial lasted several years, but none was found guilty of anything.
