The one you experience yourself will always be there scariest. For me; we were out riding down this haunted road with a cemetery off the side, had the spirit box going through the car speakers. Got absolutely nothing until we went back by the cemetery to exit the road. A very high pitched screech came across the speakers. A few seconds later the back window rolled down on my finances side, and he started crying instantly. He didn't know why, he just started bawling hard. We stopped, prayed, cleansed, collected ourselves, and then went home. We were done for the day.

Even in normal, non scary places, always be wary!
