YES!  I've seen the same thing.  Trash is very often generated by 
electronics, and by the power supplies for electronics, in a building, 
carried to the AC power line (made worse if the home is poorly 
grounded), and radiated by the power line.  If the home IS well 
grounded, radiation of the trash is primarily limited to the wiring 
inside the home (and to outside wiring like telephone, CATV, and 
satellite TV cables). .
