the urban legend machine

If only we were further along in the project (and located in England), this could be a good candidate for a house to seal, or at least test the sensors in:

A young mother has pleaded with Redbridge Council to be re-house her and her daughter because their home is haunted. ... The family from Hainault, who do not want to be named, have reported eerily similar unexplained phenomena to that experienced by [a different] girl, which the Recorder reported in January 1997. ... The sound of fighting, shouting and breaking glass, which may have blighted the home half a century ago, can still be heard claim the family. ... A family member told the Recorder this week: "Every single thing is the same as what was reported nearly a decade ago."

Of course, seeing as details of the story were reported in 1997, one could assume the current residents simply had read the news, even if they have "forgotten" it 10 years later. It would require some research down that avenue, to see if the story is "tainted," since we know how easily urban legends can start, but a house with audible manifestations, for additional verification, would be good fun to rig out.
