Piblokto

"An abrupt dissociative episode accompanied by extreme excitement of up to 30 minutes' duration and frequently followed by convulsive seizures and coma lasting up to 12 hours. This is observed primarily in arctic and subarctic Eskimo communities, although regional variations in name exist. The individual may be withdrawn or mildly irritable for a period of hours or days before the attack and will typically report complete amnesia for the attack. During the attack, the individual may tear off his or her clothing, break furniture, shout obscenities, eat feces, flee from protective shelters, or perform other irrational or dangerous acts."
