A young Sioux warrior seeking a vision went alone into the wilderness. One night, he heard singing but found no one. Later, a ghost appeared and demanded to share the warrior's food. They wrestled, with the ghost gaining strength away from the warrior's fire. The warrior kicked more wood onto the fire, weakening the ghost. The ghost conceded defeat and led the warrior to a valley of horses, fulfilling its promise of riches. The warrior believed in ghosts after this encounter.
