Re: There's a special place for people like that...
my wife an I used to live in an old thatched cottage that was rebuilt with wire-mesh and concrete between the beams - made a really good Faraday cage (for certain frequencies).
For example, I couldn't get a mobile signal in the house, nor a wi-fi signal outside the house (from the wi-fi router in the house). Wi-fi was also tricky inside the house to be honest due to the effin great double inglenook fireplace smack in the middle of the house, but hey ho.
However, this didn't stop my wife from registering EM waves from the nearby village transformer which did seriously affect her sleep - she says she could hear it, and also confirmed that the noise was absent during the odd power cut we suffered whilst living there.
Not quite sure how to prove it, but since leaving that house it hasn't been an issue, so if it was purely a psychological condition I would have thought it would have continued (my wife was unaware of the location of the transformer initially and just complained about a high pitched oscillating noise, like a sine wave, so I don't believe it was psychosomatic).
