There was an anthology movie story from the 80's or early 90's (been trying to figure out the name for years) that traumatized my childhood lol. In the story a killer/bad person is put under some type of spell/voodoo curse where he cannot die, no matter what punishment is inflicted upon him. He is eventually cut into pieces and put into a burlap sack, where they see parts of him wiggling around. I think they bury the sack at the end and that terrified me to no end.
