Godzadowi

The Godzadowi is a mystical event from the Seneca and Iroquois people. It’s described as a form of possession hysteria that commonly occurs during the midwinter festival. It’s believed that certain spirits cause different reactions in those they possess. If one is possessed by a bear spirit, they may show great strength, grunt, clench their teeth, and be calmed with berries.
