What is Ghosts in Tibetan culture?

There is widespread belief in ghosts in Tibetan culture. Ghosts are explicitly recognized in the Tibetan Buddhist religion as they were in Indian Buddhism, occupying a distinct but overlapping world to the human one, and feature in many traditional legends.When a human dies, after a period of uncertainty they may enter the ghost world.A hungry ghost has a tiny throat and huge stomach, and so can never be satisfied.Ghosts may be killed with a ritual dagger or caught in a spirit trap and burnt, thus releasing them to be reborn.Ghosts may also be exorcised, and an annual festival is held throughout Tibet for this purpose.
