First, I'm not a Jehovah's Witness, neither am I an Evangelical or Catholic. I don't speak in tongues nor swoon while singing (I can't sing), but I've had two experience with the paranormal in my lifetime and can tell you all that there are such things as spirits...bad spirits. Don't believe everything you see on television or anywhere else, but the types of things you see on Scy-Fy Channel's GHOST HUNTERS do happen. Moreover, the spirits of evil beings do seem to manifest themselves more in the Old World than New (at least most places). I've also had friends I know and trust who have had similar experiences.
I don't gain a whit if you believe me or not...I'm just sayin'.... My experiences were a long time ago.
Having said that, there are cultural stories within the Witness community, as in many others. There also are many logical explanations for many, many stories where people think they see or hear something. For one thing, I NEVER draw conclusions. I risk my own credibility when I say that my mother and I many years ago saw two UFOs flying over Washington, D.C. We've live on Air Force bases and around Navy bases all our lives. My dad's a Navy aviator. So when we see two disc-shaped objects flying in perfect formation over the Nation's capital with no markings or blinking lights, we nearly jumped out of our skins.
If you'll notice, I said UFOs, not "flying saucers" or extraterrestrial craft. Everything I can tell you is the above. We were on a hill overlooking the city (in Virginia) and the UFOs were traveling in a general north-northwest direction. They also were traveling in a skipping motion. We still have no idea what they were and I was in no mood to report them or to get my name on some crackpot list. I don't believe they were spiritual manifestations for a moment, but if someone told me they were government craft I'd believe it.
As for the spiritual manifestations, they're personal and I have no doubts about what they were. I also had witnesses in both cases. We also were fully awake and had not been asleep. There have been occasions where I awake simply terrified, but these, I think, are natural phenomenon and I don't worry about them. I also know (and GHOST HUNTERS has mentioned this) that if some people are around high EM fields and aren't shielded, they can turn into real basket cases. Ever feel like you're being watched? See something out of the corner of your eye every now and again? Don't call an exorcist, get an EMF meter and check your house out.
