I'm not a religious guy, I think most religions are just stories made up by people from the past as a means of influencing people today. But that doesn't mean I'd tell someone not to believe in there faith if it gives them something good to believe in, and results in being better people for it.
On that though, that doesn't mean I don't believe in something else out there, things that are unexplained and hard to comprehend.
When I was around 11, I remember seeing something, an apparition, in an old holiday home I stayed in. Since then I've felt it that theres something else in this world that isn't confined to science or religion that can just be explained away as nothing. Also, my mother told me when she was a teenager, she herself saw something in an old london home she lived in briefly, the visage of a woman standing at there fireplace, before she disappeared, so she herself experienced it.
I'm not someone who easily gives into flights of fancy, I don't simply believe it when any old person 'claiming' to be a spiritualist comes on t.v or writes a book that they've experienced something. I hate shows like ghost adventures, since its so obvious there making up complete bullshit in order to make a t.v show from it, so it takes a lot to convince when something seems genuine or not.
Saying that, I believe there are some genuine spiritualists out there who do experience things, like the most well know lorraine warren, and her now deceased husband Ed, who spent there lives given respect to those people who experienced cases of hauntings and supernatural activities, many of there cases simply being resolved with nothing more then its just an old house with creaking floor boards, or old pipes. That said, they did actually deal with some genuine cases of hauntings, and even helped many families resolve such cases. The recent movie, the conjuring, is based on one of there cases (soaped up for movie format of course), but both (unlike Zak Bagans obvious satire show), actually seem to be serious about these cases, and even admitting when something is fake, and when its genuine.
I do believe in spirits, such as negative energies left behind when people pass on, and maybe even stretching it to there being things not human in such cases left behind. But, I don't believe every claimed medium of it, when its obvious there just trying to make money from it.
