Ghostly Pack Coming?

Amok originated from the Malaysian/Indonesian word meng-âmuk, which when roughly defined means "to make a furious and desperate charge". According to Malaysian and Indonesian cultures, amok was rooted in a deep spiritual belief. They believed that amok was caused by the hantu belian, which was an evil tiger spirit that entered one's body and caused the heinous act. As a result of the belief, those in Indonesian culture tolerated amok and dealt with the after-effects with no ill will towards the assailant.
