I hope they are not real. Not because i'm scared or anything [I proberly would be] but because it would be horrible for souls to be lost on Earth just following the ones they have left behind..
I have been reading this book which has ghosts in, very comedic and it shows lots of possibilities about ghosts.
Sometimes you have to wonder about it being fake, all those seances and people seeing them. Although its hard to think they are make believe, because who would've made up the whole ghost concept anyway?
Very confusing, which is why I am not sure. ^^;;
