Duppy is a Jamaican Patois word of West African origin meaning ghost or spirit. Much of Caribbean folklore revolves around duppies, generally regarded as malevolent spirits.
Well, one of them is allegedly haunting an 11-year-old boy, causing commotion in Martin Street, Spanish Town. You can jump to 0:40 and then 1:55 for some duppy action. At first glance, the boy really seems to be pulled by an external force. A classic “Poltergeist” case involving a child, thrown objects and distraught families.
