World's strangest village where people fall asleep suddenly

The village Kalachi in Kazakhstan experiences a weird thing where people suddenly fall asleep while walking.

Kalachi people can fall asleep unexpectedly, sometimes for hours or even days.

They can sleep while walking or working and when they wake up, they have no knowledge of when or where they fell asleep.

For years, scientists have been puzzled by this odd condition and despite intensive research, the source of this occurrence is still unknown.

Several explanations have been offered to explain the cause of this illness. Some researchers assume that a poisonous material or gas in the village is to blame.
