If you’re an avid movie watcher, you’ve probably come across some pretty weird urban legends and myths. What’s amazing is that oftentimes real-life occurrences of mass hysteria, spurred on by mass psychogenic illness or collective obsessional behavior are much more bizarre and scary than fictional myths. These anomalous phenomena occur just like other natural phenomena and have long-lasting psychological and often fatal effects on the victims. Unusual as they are, similarly absurd phenomena are observed in animals and plants as well.

200+ Years of Witch Hunts, Trials and Executions

Most common in the Early Modern period (1480 to 1700) in Europe, witch hunts were one of the most popular and widespread forms of mass hysteria, resulting in legally sanctioned witchcraft trials and mob lynchings of many unfortunate people. The practice was so widespread that in later years absurdity of these accusations caused the term to adopt a connotation of malicious false accusations and persecution such as the anti-communist accusations during the McCarthy era.

The War of the Worlds Martian Invasion

Adapted from H. G. Wells’ famous novel The War of the Worlds, a Halloween radio broadcast on October 30, 1938 directed and narrated by Orson Welles caused thousands of listeners to believe that an actual Martian invasion was taking place (the fact that the environment was already generally hostile, leading up to the war, didn’t help). The hour-long radio broadcast was narrated in a news bulletin format, without any commercial breaks, causing many in the audience to be afraid while many others actually panicked, reporting that they could smell poison gas or see lightening flashes in the distance. According to some historians, approximately 6 million people heard the broadcast, 1.7 million thought it was true, and out of those, 1.2 million were actually frightened.

The Tanganyika Laughter Epidemic

This laughter epidemic started in a Tanzanian village in 1962. Starting with an innocent joke in a boarding school, the resulting laughter is said to have perpetuated itself and spreading to thousands of people.

The situation got so serious that the Scotland Yard had to step in to help the police and get to the bottom of these reports. Several people were mistakenly identified as the slasher and consequently beaten up by angry mobs and matters escalated to a point where most businesses in the city were shutdown and people were afraid to leave their homes. On November 29, one of the original alleged victims admitted that he had made the story up, causing many others to also confess and leading to 5 people being charged with public mischief out of which 4 were eventually sent to prison.
