This is a weird one, even by our standards. In Indonesia, there is a region called Toraja, where an old ritual still continues to this day.
Every three years the people of this very secluded province unbury their dead and dress them in clean clothes to parade through the village, like something out of day of the dead.
Its like a real life zombie movie, except these dead people are not trying to take chunks of flesh out nearby people.
It must be hard to see a dead relatives standing in front of you, dressed like they are ready for the day ahead.
The corpses are given a brush down every 3 years to keep them in good condition.
The reason for the locals carrying out this strange act is to actually to show respect to the dead, and prove to everyone else that their ancestors are not forgotten.
Its interesting how different cultures have different views on death. In the ceremony called Ma’nene, the body is out of its resting place for a day, then returned to the coffin.
