Thai Buddhism is impregnated by ghosts stories coming from Buddhist legends. But it is also impregnated by ghosts stories coming from old religions present before Buddhism in Thailand. There is a belief into two kinds of Thai ghosts and spirits :

- Ghosts linked to the Nature and its elements (air, earth, fire and water)
- Ghosts linked to Buddhist beliefs and legends

Thai people are really afraid of ghosts ("PHI" - ผี). No joke should be said about them otherwise they might come. Anyway numerous Thai magazines about ghosts and spirits are available in Thai bookshops.
