History is full of weird incidents of mass hysteria, where insanity from person to person, or took over a whole community at once. Here are the most uncanny incidents of shared insanity.

Some listeners heard only a part of the broadcast and took it to be a real news broadcast — causing a wave of mass hysteria across tens of thousands of radio listeners. There were traffic jams, phone lines and electricity went out, and some families fled their homes to hide in nearby parks.

You can listen the whole radio drama here.

A woman named Frau Troffea just began to dance in the street, for no reason. After a few days, more than 30 others had been joined in, and within a month there were around 400 dancing people. This dance lasted for days without rest, so many of those people died of heart attacks, strokes or exhaustion.

A nine year old girl, Betty Parris, and her eleven year-old cousin Abigail Williams began to have fits described as "beyond the power of Epileptic Fits or natural disease to effect" – they screamed, crawled, threw some things and uttered strange sounds. Later, other young girls began to exhibit similar behaviors. Over 150 people were arrested and imprisoned. 19 of them were hanged, one was crushed to death, and more than ten accused witches died in prison.

Everybody Freak Out: Strange and Uncanny Outbreaks of Shared Insanity

About 8pm somebody claimed that the seawater at Mahim Creek, one of the most polluted creeks in India had turned sweet, not far from the shrine of the famous Muslim Scholar named Haji Maqdoom Baba. And then at midnight, some others claimed that seawater at Teethal beach had turned sweet as well. The local goverment warned people not to drink the water, because that could cause waterborne diseases, but thousands of people started to collect it. On the next morning people admitted that the water was less sweet, and at 2pm, everybody agreed the water had "turned salty again."

Penises are Being Stolen in villages in the Central African Republic, 2013

Everybody Freak Out: Strange and Uncanny Outbreaks of Shared Insanity

A common fear since the Middle Ages — but still alive in Africa, according to anthropologist Louisa Lombard:

"Elaborate greetings are the norm, I’ve found, when one enters a Central African village. So it was a surprise when I noticed that many people weren’t shaking hands the morning I arrived in Tiringoulou, a town of about 2,000 people in one of the remotest corners of the Central African Republic, in March 2010. I soon found out the reason: the day before, a traveler passing through town on a Sudanese merchant truck had, with a simple handshake, removed two men’s penises.

As best I could reconstruct from witness accounts, the stranger had stopped to purchase a cup of tea at the market. After handing over his money, he clasped the vendor’s hand. The tea seller felt an electric tingling course through his body and immediately sensed that his penis had shrunk to a size smaller than that of a baby’s. His yells quickly drew a crowd. Somehow in the fray a second man fell victim as well.

[...]

Reports of genital theft have spread like an epidemic across West and Central Africa over the past two decades, in tandem with what appears to be a general resurgence of witchcraft on the continent."
