I think that there are just too many sightings by people to ignore that there may possibly be another dimension that we humans can't get scientific evidence on! I grew up in an area that was near a famous battleground during the Civil War...I knew many credible people that had seen some out of the ordinary things! Like an old soldier on a horse, etc. that type of thing. I believe that there are a lot more stories out there, but because of how you get treated if you say anything, like in this thread, people just keep it to themselves.
That being said..I've had a few sightings myself and I know what I saw!!! I hadn't been drinking, doing drugs, etc., etc. As a matter of fact, a few months ago, I saw a man on my brother's sofa that looked just like my brother. He disappeared shortly before my brother walked out of his bedroom! My brother had just woke up and had slept in his bed the entire night.
EXPLAIN THAT!!!
(If I had known that it wasn't my brother, I would have tried to scratch him and get some DNA under my nails for scientific evidence!)
Like I've said before, when you have seen "something" it makes you a believer, but if you haven't, then you don't. It's kind of like getting the JW's to realize the "truth" about the "truth"...until they're ready, there's not much you can do.
