Mullo (Muli: female, Mulo: male) is an undead, revenant, or vampire of Roma folklore. 'Mullo' means 'one who is dead'. A mullo is created when a person dies suddenly of some unnatural cause or the person did not have proper funeral rites. A mullo is described as having white clothes, hair that reaches to their feet, and one physical oddity (a trait which varies from geographic region to region). A mullo's existence is in seeking out people it did not like in life and harassing that person.
