It's scary to imagine that one day; we will be running for our lives because zombies are going after us. But here is a story of an ethnic group called Toraja in South Sulawesi, Indonesia where the existence of real walking dead could be found.
The people in this place have a special ritual that takes place in August. Ma'nene they said is more important than birthdays or weddings for Torajans. In this ceremony, families dig up the corpse of their loved ones, wash, groom, and dress them in new clothes. Then, the mummies are walked around the community since they believe that a dead person should go back to their homes. There are 3 ways of burial for Torajans, the coffin may be placed inside the caves, hung on a cliff or in a carved stone grave. They do this so they can get back their deceased loved ones' body easily. They even have wood-carved effigies overlooking the village, called Tau tau which is made for the notable people of their community. After the ceremony, the corpses are returned to their gravesite.
This ritual sound disgusting or unhygienic for us, but for Torajans, it is a part of their identity.
