People always talk about GHOSTS but its us whether we want to believe it or not. Since we were born, our people or storyteller keep feeding us with all these GHOST stories until it really instills in our mind and we really believe it. But when talks about logic or scientific, these myths are not exist at all. We are the ones who keep these things bear in our mind. Let's take one example, lochness, which in my opinion doesn't exist at all. It exists only when we started to think about it or we doubt about it.
