"In my opinion, I think ghosts do what they do because they are pissed off that they are dead.
And when they are dead, they think back they have unfinished business they need to take care of. And that is, torturing the living among them that soon arrives shortly after their death.
And I don't blame some ghosts, they torture because they want people to get the hell off their property!
But sometimes, they are just clue less and upset because they don't really know that they are dead, they can't help it.
Some ghosts are good some are bad あなた can't do anything about it.
Now I don't know about hauntings, but as far as that goes, most ghost do that when their angry.
I'm not really a big believer in ghosts because I haven't seen one for myself before for a real experience.
But I do believe that they are out there, and they are trying to find their paths, and they need help to do that".
