[Spiderman]

Hmmm, i'd always been unsure about this until i started seeing a girl who's place was haunted. She lived at home with her mum and dad & 2 brothers at the time.
They all knew about the ghost and had grown up with him in the house and he'd never bothered them...just gone about his business of walking about upstairs when everyone else was downstairs.

Then i stayed over for a night or 2 while she had the house to herself and got to winess/experience it for myself.

now i KNOW that they do exist. Not all ghosts are "nasty" or "evil" and like mrs24_7 said most poltergiests like to hang out with or latch onto pre-pubescent girs if there is one in the family. Its almost like they never stopped or accepted they dont live anymore and stay on this plane instead of passing over to the other side and resting themselves for whatever comes after that.

I could tell you loads of things about that ghost but i wont bore you.
