4 Strange and bizarre Events

Dancing death

In July of 1518, a woman referred to as Frau Troffea stepped into a narrow street in Strasbourg, France and began a fervent dancing vigil that lasted between four and six days. By the end of the week, 34 others had joined her and, within a month, the crowd of dancing, hopping and leaping individuals had swelled to 400.
Authorities prescribed “more dancing” to cure the tormented movers but, by summer’s end, dozens in the Alsatian city had died of heart attacks, strokes and sheer exhaustion due to nonstop dancing.
For centuries this bizarre event, known variously as the dancing plague or epidemic of 1518, has stumped scientists attempting to find a cause for the mindless, intense and ultimately deadly dance.

Tanganyika Laughter Epidemic

Perhaps the most unusual documented case of mass psychogenic illness was the Tanganyika Laughter Epidemic of 1962. A paper published the following year in the Central African Journal of Medicine described what happened.
Triggered by a joke among students at a Tanzania boarding school, young girls began to laugh uncontrollably. At first there were spurts of laughter, which extended to hours and then days.
The victims, virtually all female, suffered pain, fainting, respiratory problems, rashes and crying attacks, all related to the hysterical laughter. Proving the old adage that laughter can be contagious, the epidemic spread to the parents of the students as well as to other schools and surrounding villages.
Eighteen months passed before the laughter epidemic ended.

Raining Animals

Yes, it has rained frogs in real life, not just in the movie Magnolia. Birds, bats, fish and even worms have been reported to fall from the sky. Scientists theorize that fast-moving storms and waterspouts cross a body of water and sweep or suck up animals, then deposit them miles away. Residents of Honduras have celebrated the Lluvia de Peces (Rain of Fish) annually for more than a century. The fish are believed to be sucked up from the ocean and deposited 140 miles inland, while others have indicated that the fish may be from underground water sources.

The most polluted creeks in India,had suddenly turned “sweet”

The 2006Mumbai “sweet” seawater incident was a phenomenon during which residents of Mumbai claimed that the water at Mahim Creek, one of the most polluted creeks in India that receives thousands of tonnes of raw sewage and industrial waste every day had suddenly turned “sweet”. Within hours, residents of Gujarat claimed that seawater at Teethal beach had turned sweet as well.
The Maharashtra Pollution Control Board had warned people not to drink the water, but despite this many people had collected it in bottles, even as plastic and rubbish had drifted by on the current. By 2pm the following day, the devotees said that the water was salty again.
