When I was 18 in my first house, I got in from work and was making a cuppa tea, as you do, when my stereo switched on playing really scary organ music, this was the beginning of the Faith Track by George Michael, just as the song was about to start, the stereo switched off completely!! In my panic I grabbed my cuppa and sat on the step of my front door awaiting my macho hubbie to come home from work.
When I told him he burst out laughing, as the stereo was new, he had been trying to program it to wake us up in the morning by getting it to play for a minute in the morning, but had set the time to 6pm instead of 6am!!!
I think that most JWs are a little paranoid, to things and there is usually a perfectly good explanation. When you hear these stories it is usually a friend of a friend.
For those who have had bizzare experiences, I am not calling you paranoid, I'm too new to this site to make enemies!!!
