Do gohsts exists

I believe your question is; "Do GHOSTS exist?"

That is debatable. I have not seen any ghosts, but i believe in the possibility that they exist. And there are videos of unexplained phenomena that support my claim.

Although I think most of the visible ones are fake.

One theory: Ghosts are those who have unfinished business on earth, or are rejected by both heaven (not good enough) and hell (not bad enough)
