A Pishacha is a type of supernatural being in Hindu and Buddhist mythology, often depicted as a malevolent spirit or ghost. These entities are believed to haunt graveyards and desolate places, preying on the living. They are typically associated with darkness and are said to have a grotesque appearance, sometimes resembling a corpse. In folklore, Pishachas are known to possess individuals, causing madness or illness. They are often linked to the practice of black magic and are thought to feed on the life force of their victims. The concept of Pishacha is part of a broader belief system that includes various spirits and deities, such as Brahma and Shiva.
