Hey. I hope this will make you pick as a best answer.
Life occurs, by thinking twice, and having second chances. The possibilities, and stories people come up with are endless, and situations and problems are also endless. But coming to Christianity and Ghosts. I'm a Christian, but I do not want to comment whether I believe in ghosts or not. The stories, and the videos people use, are either a photoshop or actually real, but you cannot judge that with a statement unless you have proof of it, for real.
On the other hand, you have other things. People thought Santa Claus was real, but he wasn't. I believe in God, but some people do not, and some people believe in different sources of God. You can't tell whether the whole witness is cycological. But God made us for who we are, and to grow up thinking mysterious thoughts, and evaluating our question until our death. We will not know, whether God is real (But I still believe in him) until we die. We won't know whether... Henry 1VV really did play tennis. We don't know, that the Muslims were right.
This is my story. We cannot, and simply cannot, tell whether these thoughts and cycological stories are real. Mythyical things; Vampires also have a distraught feeling to the world. When people grow up, someitmes they have long 'fang' teeth, or they are pale with very dark eyes, therefore they would like to be known as a vampire, although they are not, they are human. But we cannot tell, whether there are Vampires in other planets. We don't know, that there are witches on other planets, or any other Mythological creature. Our human mind, and our ability to witness things, gives us a smart, yet curious idea.
So the answer to your question: Nobody knows until we die.
Thanks for reading this, and I hope I helped to please your satisfaction.
