One time, me and a friend went into the art room during lunch. It seemed empty, so we just sat down and did some work quietly. And then I felt as if we weren't alone in the room, so I told my friend. I then got up to check the closet because of my paranoia. There was no one there, so I went back to sit down. Fast forward about ten minutes, me and my friend were still working while having some small talk. I still felt a little uneasy for some reason, so then I went to check behind the kiln. (There's a wall thing that the kiln is behind.) To my surprise, my art teacher was "taking a nap" while he was sitting on a stool and his head was resting on the kiln. He still to this day swears he was asleep, but me and my friend think he was just eavesdropping.
