The other night our treadmill, which does not feature any audio setting (with the exception of a "beep" sound) started broadcasting a radio signal, it was the freakiest thing. I was flushing the toilet, and all of a sudden I loudly heard "THE OFFER ENDS AT MIDNIGHT, (something something etc)," it was the most bizarre signal interference I've ever been witness to. It was my own Max Headroom incident. I only knew what was happening because I used to record with a karaoke machine and it would sometimes pick up a signal from CBs. I don't believe in supernatural occurrences, but I guess I was spooked enough where I still had a dream that night about our appliances coming to life.
