JD Lion, When I said "I personally don't believe in ghosts." I mean't by that, I don't believe in spirts of dead people that come back to haunt the living. When you die you either go to heaven or hell.
Religion is a touchy subject for some here, but, since we are talking about my beliefs, here is what I think in more full detail. Some of these things reported can be explained naturally. Others where people actually see "ghosts" and floating objects and such, I would say are one of two things, imagination running away (Many people you see on tv documentaries are often crazy looking) OR demons posing as dead people (ghosts). I believe in God, I also believe there is a devil who has his own legion of angels doing misdeeds on earth and leading mortals astray and tormenting them. Such things are indeed recorded in Holy Scripture.
I believe most of these people, including you, are seeing something. I believe you saw something unique that night. BUT I don't think it is the spirit of a dead person come back to life (I think it is something much more dangerous if you let it, or downright harmless if you know the Truth that sets men free).
"hostile ghosts" I would say are tormentors of the lost and drawing attention to themselves away from God.
"Friendly ghosts" that are "non violent" I would say are likewise setting themselves up to be worshipped (by that I don't mean bow down literally and pay homage to it, but many people get obsessed with it and even call seeing them "spiritual experiences".) Bottom line, from a Christian worldview, they are drawing attention away from Christ and towards another false idol. If the supernatural event is not pointing to Christ then it is a lie. (Remember heavenly angels always came as messengers of the Lord and made that perfectly understood)
Anyway,
Back on topic. So you pulled a gun on a ghost! Wow. Like I said, I believe you saw something alright. I would probably have urine running down my leg after I saw that.
I read of an incident in Jefferson, Texas in which a man got into his car and found a ghost man sitting right next to him in the passenger seat smiling at him and fading away
(lot's of eerie ghost stories in Jefferson, especially at it's downtown hotel)
