So this happened to me
 

So I do this Shockumentry series on youtube. I've been doing it for years now. I'll be honest with you when I say that the dark scares me. While shooting this series I often have to be in the dark. One time something happened. I was in pitch dark when a sequence of mystery noises scared the piss out of me. The first noise sounded like a girl was startled and the second noise sounded like fingernails being dragged against the wall. This is real. And this isn't some jump scare trick. I have video of it, but the nails dragging noise wasn't picked up on my camera that I know of. I can't hear it on the video anyway. I do quickly turn and focus the camera in the direction of the noise. I just figured that this might be fun for you guys to see. It is a bit embarrassing, but it was thrilling too.
