The village of Kalechi is located in the north of Kazakhstan, 230 km from the Russian border, and 300 km from the west of the Kazakh capital Astana. Scientists have been baffled by the sudden sleep that occurs to its residents, who sleep while working, driving, or talking with others.
The villagers do not sleep for a few moments or hours, as their slumber lasts from two to six days, and when they wake up they are not aware of what happened to them.
Despite efforts to find out the reason behind this, scientists are still unable to explain it.
