Do We Need A Thermal Sweep?
I caught a few episodes of Ghost Hunters, featuring the the group that seems very popular in America these days.....TAPS (The Atlantic Paranormal Society). It is a good name as the two key figures are also plumbers. Each vigil is of course done in the dark and starts off with a "thermal sweep" with somekind of thermal camera that picks up heat signatures. Sometimes these pick up what may be 'ghosts', looking amazingly like a person.
So, are these ghosts likely to be members of the film crew? Does anyone actually know of a ghost that gives of a heat signature?
I've never done a thermal sweep before of any location I have been involved in investigating. Is it a good idea?
