I've never seen a ghost, nor do I believe in the paranormal. It's hard to believe in something you've never seen. I have very strong beliefs in this subject. Basically, when it all boils down to it, I believe that every single person who thinks they have had a paranormal experience is either:
A) Imagining things.
B) They let their minds run away from them for a split second.
C) Were intoxicated or had sleep-deprivation.
D) Saw something in the corner of their eye and are exaggerating it into huge proportions.
E) Wanted to see a ghost or the paranormal so badly that when they saw something that could be scientifically explained, they discarded it as a ghost instead.
I get a lot of arguments over this, but it's just the way I feel. I've seen many "shadowy figures" in my day, and they were all able to explained after a couple of minutes of thought. All the paranormal activities I've experienced can be explained in some way, shape, or form.
Disclaimer: No, I'm not ignorant. I just find ghosts and the such hard to believe in. Logic would tell you that if there isn't proof, it doesn't exist
Then the whole religion thing kicks in....but I think ghosts and religion are two entirely seperate entities
