The Bell Witch Haunting

my friend told me a story, when he was younger he went into the mountains behind his house with a friend, he said they were a long ways up in there, he said he started hearing music playing, and looked at his friend and said do you hear that, he said yes and looked a bit scared, he said the music was inviting, so they started following it, they then found a little girl in the woods, just sitting there singing, he started walking towards it, and then got this feeling like something said fucking run or your dead, he said he did, he never had a terrifying feeling like that before, then he said he could feel the girl he saw in the woods chasing him, he didn't want to turn around, but he did, when he saw it, he said it was the most ugly thing he ever saw in his life, looked like a demon or something he can't explain what it looks like, he said it was flying to, but he said he kept running and got to a safe point, he said when he got there the girl could not chase him no more, like there was a invisible wall, this is the story he told me, he never lies, so I do believe him, also we do live in TN. it's very fucked up, and when he told me this story he looked like he was getting scared of it again, can't explain it at all.
