I have seen quite a few places cleansed of activity. Such was never my area of interest. The places I have went were to document activity, find an explanation if there was one and to investigate how the unexplainable exists. My interest has always been in the underlying physics or meta-physics of the unseen dimensions. I leave the cleansing to others. But I do believe that evil is as real in the other dimensions as it is in the world of the living.
