I believe something like that exists. There are far too many things unexplained by science for us to disregard it.
I personally believe there is something, not saying "ghosts" but I believe there is somethign we as humans cannot destinguish which most class as ghosts. When I was younger, most nights, a dark shadow would sit at the end of my bed - I knew it was sitting on my bed because I could feel the bed dipping down at the end. Also last year while at my partners house a knock was on the bedroom door and no one was behind the door. Me, my boyfriend and his two mates heard it too.. so I wasn't the only one. So there is defenately something, just knowing what it is is the question!
I've not seen any ghost yet, but I had the very strange case many years ago. I'm sure, ghosts isn't a myth. Anyway, I don't believe in every story about ones.
I do believe in ghosts because I have had personal encounters. One of my stories is theHaunted House For Sale - I wasnt the only one who was involved either and it happened several times, so no way was it my imagination.
I don't believe in ghost. For one good reason "I still don't have any encounters" but if ever I will meet some ghost. I will keep you guys updated
I have an open mind about them. Although I have never had an experience with ghosts myself, I know friends who have had experiences.
