Rolling Hills Case Manager, Suzie Yencer relates one chilling experience: "It was September 2007. While working a public hunt, we had a gentleman with us that was filming a documentary about the building. He wanted to try an experiment in one of the rooms. The room he chose was in the basement, popularly known as The Christmas Room. The experiment he wanted to try was to sit in the room with no lights or equipment on. The only light we would use was a pink glow stick in the middle of a circle of people. We also placed a small ball and a toddler size rocking horse in the circle. The gentleman conducting the experiment requested that only I talk and try to make contact with the spirits. The more I talked, the more strange occurrences began to happen. The glow stick started to move back and forth, and the rocking horse began to slowly rock. A few of the guests in the room including myself saw a hand and arm come out of nowhere and reach for the ball in the circle and then just vanish...."
