"turn on the flashlight"

After the bird incident, we hid out in the bull pen for a while before heading into solitary. When we entered solitary, we realized we were not alone.
There was another group on one end, trying to communicate with spirits by asking the spirits to turn their flashlight on. I didn't want to interrupt, but I did want to see if it worked so we went down the other side of the cell blocks to meet them at the back of the wing. I was trying to listen and see if the flashlight went on so I made us turn off our lights. I tried to be as quiet as possible but when they started asking if anyone was there, I didn't know whether to answer or whether they were "communicating" with a spirit. I turned the corner at the end of the cellblock and heard a gasp and turned. About five infrared flashlights were shining at me and the people who held them were paralyzed with fear. after letting them know I was human, I apologized, and we slunk upstairs. They started back up again.

Update: we are in the visiting area and there are metal folding chairs in the room with us and they've started pinging or squeaking even though no one is sitting on them!!
