Possession
Closely linked to ghosts is also the topic of possession. In some areas in Thailand, families have their own family guardian spirits. They are usually consulted through family mediums who are advising people in trance. One kind of family spirit is always kept secret though, it is the "phii kin kon" ('ghost who eats people). A family who has this protective spirit has to observe some very special rules, and people marrying into a family having this spirit as a guardian are said not to have a very long life.
And when haunted houses need exorcising, specially trained people are called in, who with the aid of a tool called "mai song" can pin point the graves of people. During those ceremonies some protective deities are moving into the "mai song", and possess the arms of the handlers (there are always two). The exorcism is an enormously energetic activity, where the spirits are exorcised with a lot of noise and running around.
