Many times this would happen in the middle of the night, waking me up and freaking me out. It happened once when my girlfriend (now my wife) was over and it freaked her out completely to where she wouldn't stay there that night.

Since I am skeptical about the paranormal I decided to see if I could figure out what was causing it. I noticed it seemed to happen when semis drove down the road in front of the building. Then a few weeks later I understood some of the gibberish, something about "Highway 45". It turns out it was truckers with super-powerful CB's, somehow the stereo interpreted that as a signal to turn on, and these truckers voices would blast through at full volume.

So what does that have to do with this thread? I don't know. I guess it shows that weird stuff can turn electrical devices on and off.
