Here’s what you’ll learn when you read this story:A late Neolithic or Early Bronze Age grave has revealed ancient strategies to keep the dead from turning into “revenants” and disturbing the living. Placing individuals in certain positions to help keep them in the grave was a custom dating back thousands of years. The grave makers of the Early Bronze Age had their own strategies for keeping the dead... well ... dead. One such “zombie grave” was recently found in Oppin, Germany, according to a Facebook post from the State Office for Heritage Management and Archaeology of Saxony-Anhalt. “We know that already in the Stone Age people were afraid of revenants,” Susanne Friederich, an archaeologist with the state office and project manager for the excavations told Newsweek.
