I worked on GHOST ADVENTURES on 1 full season years ago.
I unluckily was one of those idiots who had to roll the cable for the cameras in every room for a lockdown’. I believe in this sh*t. One example we were on the ground level in a room with no light on a certain “prison” and while rolling the cable a black mist walked in front of me and hit my baseball cap.
Prisons would creep me out. They tend to have alot of negative energy due to the prison residents and the crimes they have committed to have them being there.
