I think ghosts exist whether you like it or not. Its not about me giving you evidence about ghost's existence but about experiencing. Some people do not experience such meeting with ghosts and they claim that ghosts cannot exist. Some people who did not meet with ghosts might say that ghosts exist. People who met with ghosts might refuse in believing into ghosts but others who've met ghosts might easily believe into ghosts. First of all, there is no need to believe into existence of ghosts. Second of all, ghosts exist the same way as G-d; you cannot provide enough of evidence and facts that ghosts and/or G-d exist. Why did I put G-d into this discussion? People fear the truth. Believe me: "Everyone seeks the truth but whoever proclaims the truth deceives the truth." Science cannot fully provide facts and evidences that ghosts exist. Believe into what you want to believe but there is something you do not know. Don't fear something you don't know and don't easily fall to believe into something you don't know. I've had enough of strange experiences in life which make me believe in ghosts but it is unimportant. Anyways, it actually depends on you. If you believe in them, they're there. Ghosts are nothing to be afraid of, ghosts are just like us. Ghosts are actaully dead spirits that has no where to stay (this means that when a person dies and the body is burned and placed in a place like burried, ghosts are spirits that are not buried or have no where to stay). Some humans are good and some are bad right? Ghosts are like that too, some are good some are bad. Not all ghosts are bad.
