I worked with a lady once who was pretty old, I'd say about 70 years old. Since our job was pretty boring, we talked a lot and she had all kinds of crazy stories. But this one creeps me out still. She said when her grandma died they had her buried in a wood box in the backyard, as was pretty custom in those days. Well years later they have a family plot in a cemetery and decide to dig her grandma up to move her to the family plot. She said when they took the lid off the coffin, it had claw marks all over the inside. The grandma had apparently been buried alive.
