Death as the Cause of Mischievous Spirits

This was probably about a hundred years ago. It was old woman Berg who told me about it, and it had happened in her youth, and she was very old. It was people from Voijen who were here in the churchyard digging for a body when they unearthed a skeleton. The farmhand picked it up with his spade and started to "play superstitious tricks" with it, so he must have taken a bone fragment with him, because after that day, there was "mischievous activity" on the farm. The mistress of the house understood what it was due to and forced the farmhand to take the bone fragment back. After that, it became peaceful.
