Last days I had to shield a lot the mainswitch of my powersupply in my flat. Today no stress was coming from it. When I shielded it I thought my sensivity has gone up which is real, but there is probability that over it comes stress designed for harassment. I need information about how this is possible and who has access to this. It may have been a socket which is on the opposite site of the wall close to the mainswitch in the flat next to mine.
