I had a client years ago who requested remote dowsing of their home in Minneapolis, MN, USA. They were having several problems with poltergeists, slamming refrigerator doors, moving furniture, starting or stopping their car in the garage, etc. I dowsed the place remotely using their sketch of the place and found numerous geopathic pathways. Since I had previous experience in removing a Primary Hartmann Line in a home which caused a chair-occupying ghost to move on, I decided to try the same in this case. When the requisite L-rods were installed along the pathways, warping them around the home and garage, the client reported that the spirits weren't happy about the new situation, and all but one, which was very attached to a particular piece of antique furniture, moved on. She got rid of the antique cabinet. Case closed, as far as I know.
This may not work in every case but some energy pathways and junctions seem to attract left-over human or animal energies. I've lived in two haunted houses so this prospect doesn't bother me, but when the other residents started to get too noisy I'd just talk to them about it and the situation calmed back down. I tried to find the history of who died and how it happened so I could better relate to their viewpoint of some stranger moving in. Maybe that helped. Now I just reroute the energies that seem to fix them in place.
In related news, a condominium resident in Tampa, Florida, USA did a remote dowsing and diversion a couple of years ago. Besides finding that their next-door neighbor had a big sinkhole under their condo, they also immediately noticed a large flock (murder?) of crows now spending each evening perching, talking, and spending the night on their rooftop. At first it bothered them, until they realized that the birds were both an indicator of cleared energy pathways and a sign that their home was now a preferred piece of real estate.
