I will swear by this until the day i die: when i was a kid, I was riding my bike on some hills next to a bayou with my brother. I crashed at the bottom of one and while trying to straighten my handle bars, a little girl with a German shepherd was standing on the hill i had just come down and asked what we were doing there. We said just riding and she said we shouldn't be there because a little girl was killed over there and pointed into the grass. We looked, she was gone, we ran to the top of the hill and there was nothing. It was about 75 yards of open space to the road and fence. Ghost or a brilliant prank pulled off by someone that never took credit for it.
