I also agree that science alone cannot measure things of a spiritual measure. Sounds like at interesting book, Moonlight.
I have had a few odd experiences with electrical things. During my college years, my parents had a home that I believe was truly haunted. One evening, I had gone to my bedroom, turned my radio on to my usual rock station and laid down on my bed to study. Shortly afterwards my radio started blaring Big Band era music from another station. I got up, changed it back and it occured once more. By that time, I was a little perturbed so I unplugged the radio. What was interesting, was for about 30 seconds after unplugging it, the music continued to play. Incidentally, the spirit that we thought haunted that house, would have been of the generation that appreciated that type of music.
On another occasion, a few years ago, my husband had bought me a EMF meter. I was pretty excited to try it out, so we went to an old cemetery reputed to be haunted. The meter went nuts as I walked around the place. At that time, the car I was driving had a cruise control switch that was stuck. I had tried numerous times to move it, as had my rather large, strong husband. Neither of us could make it budge. As I got back in my car that evening to drive home, something made me try out the cruise control switch. It went into place like nothing had ever been wrong with it. Perhaps the kindly spirit of a mechanic?
I've also stayed in a haunted hotel where the TV would come on and off by itself, I've had lights flicker in only one room of my home. My doorbell would go berserk when no one was anywhere near it. I've heard several stories about seeing faces on their computers, televisions, etc... So yes, I definetly believe spirits can manipulate electronic and technological gadgets.
