Nobody really knows that ghosts are or are not hallucinations. We are able to assume and make educational guesses. Some people - like I - look them up in order to find the real ones, such as people walking by who are not really there as a human being, exorcism, demons, and the things they can move and touch without you seeing the ghosts themselves.

No, there is no scientific evidence that directly proves that ghosts exist. It is just folklore.

If you believe in ghosts, than there are many ghosts in the world. There is not an exact answer because some move on just as some die and become ghosts.
just remember: Ghosts are probably not were you are
Ghosts can be anywhere! Look out, theres one behind you!!! :) JK(Just Kidding :))
