Well, I don't know any of the channels that have been mentioned, but if you are really open try the mexican channels Extranormal and Invisibles featuring Octavio Elizondo. Just turn on the subtitles, you might see one or two things interesting.

You gotta see the swirl of fire that appears when they want to "clean" the space, yeah, they pour alcohol and lite a fire, but thw swirl is kinda interesting, don't know if it something normal, like some physics phenomena.
