I wonder how many people believe in ghost existence. In my opinion, ghosts are exist but different countries different ghosts. For example, if you are in Japan, you won't see any European ghosts there. Ghosts are like human race, there are many kinds of them. But the thing is we can't see them with our eyes because that thing is very smooth and there's something that forbidden us to see them. The point is, we must believe that not only humans live in this earth but there's something else.
