Yeah I believe in it. I'm not the kind of person where something happens though, and is just like "OMG GHOST!!", I'll try to explain it first, and if I can't I still don't normally jump on the bandwagon saying ghost/paranormal. But c'mon, weird stuff does happen that you cannot fully explain sometimes, shit happens.
I've tried to find haunted places around where I live to visit, but most of them if you get caught on the property, it's a federal offense. Only been to 1 "haunted" place around here, and yeah weird stuff happened, but I'm not going to say it was "paranormal" stuff, but most definitely weird.
I do believe though, that a good amount of "paranormal" stuff that happens to people, is all in their head. Seeing and/or hearing what they WANT, not what IS.
Just my views on the topic.
