i do believe them
i can honestly say ive seen a ghost myself.
my mums finace committed suicide back in 97 i think it was, via gasing himself in the car in the garage, about a week before this all happened i had a dream that someone close was going to die, i didnt know how,when or where, then yeah a week later that happened. not long after it all (after the funeral etc) i was in bed trying to get to sleep when i have looked down at the end of my bed and there was a ghost there, couldnt see a face or anything like that, had a big hood on. after that had happend, all i kept hearing was "im sorry, im sorry", "it wasnt meant to be this way"
and yes it all freaked me out at the time,
just made me believe that they do exist and they are not something to muck around with as they can be quite powerful beings.
