Paranomal Hot Spots and Haunted Places

A group of young guys from nevada are contacting ghosts. They use a lot of interesting toys and gad s to wander around paranomal hot spots or haunted places. The most recent episode was very interesting, because there was the chirp, growling. And also, at one stage, right near the end of the episode, they hear in the distance what they think is laughter,. But to me, it sounds very much like these, a high pitched, sort of monkey like or fox like sounds that they make.
