I lived in a national park by myself for three months. Several times when I was going back to my trailer for the day, I would hear music like a music box or an ice cream truck. It was always loud and sounded like it was coming from somewhere over my head. One day I decided to look for the source so I followed the dirt road past my trailer. The music continued, I couldn’t tell if I was getting closer or not. I had my eyes on the trees and looked down just in time to avoid stepping on a snake. I scrambled back but it didn’t move. I realized it was dead and it wasn’t alone, there were half a dozen dead copperheads stretched out in the road, looking in the same direction.
I went back to get my car because I couldn’t bring myself to step over them, but by the time I got my keys, the music had stopped and I didn’t hear it again.
Sometime after this happened, my friends told me there was a haunted prison in the same park, the Pea Farm. So, that was good to know.
