Iseman wasn't the only one dealing with strange lighting malfunctions, either. McKenna Grace, who plays young Judy Warren, told me a similar story about her own quarters.
"One night, whenever we had trailers, we came back from shooting. I'm pretty sure it was the day we shot the scene with the priest ghost. [Editor's note: I don't know what the priest ghost is, and I'm not sure I want to know.] We came back, and my trailer lights were off, and they wouldn't turn back on. And it smelled in there. It smelled bad in our trailer, and the lights wouldn't turn on.
So we had to call someone over to help us get them back on. And they were like, 'That's weird. Everything's fine. They shouldn't be off.' And the trailer right next to us, the school room, the lights were on. And they couldn't figure it out. And after 10 minutes of figuring it out, they turned on. A little creepy."
