“Hello I’m Laura and I collected this story myself when I was 12 years old. It says that some girls and boys were at the party and there was a graveyard down the road and they were talking how scary it was. And one of the boys said: “Don’t ever stand on the grave up that yard because the person inside will grab you, will pull you under and so on”. And then one of the girls said it was all just superstition and she will actually do it right now. So the boy handed her knife and said that she needs to stick it into the ground because that’s how they are going to know that she really went there. So she went there and picked out a grave and stood on it. Then quickly she bends over and puts the knife in the soil and started to leave but she couldn’t get away, couldn’t move, something was holding her back. So when she didn’t come back the others went to look for her and they found only her clothes being pinned to the ground with a knife.”

Yeah, this was in Scary Stories to Tell in the Dark. I figured this might be something different, but that’s a negative.
