This story was told to me by my father when I was a little girl. My father was a teenager when all of the sudden he fell very ill. He lived in a small village and none of the doctors could figure out what was wrong with him. Someone suggested calling a "witch doctor". When the witch doctor came to see my sick father, he told him that there's something wrong and that they needed to go visit the grave of my father's grandfather. When the family visited the gravesite and dug up the coffin, they noticed that a nearby tree's roots had torn through the coffin and tangled itself around the remains of my greatgrandfather. They removed the coffin and reburied it in place that the witch doctor had suggested. The next day, my father got well right away as if nothing was ever wrong with him. The spirit of my greatgrandfather must've been trying to let everyone know that he wasn't well by reaching my father. I don't know about you but when I heard this story I was pretty spooked.
