the mind only relies on it's past and present experiences and no more...so if it encounters any strange phenomena..it will process it and match it with anythign close to it that it has experienced whether verbal, auditory, physically or imagewise..so my point is all negative chuva emotions that you have..demons, evil, satan and other so called malevolent beings will come to life because you have experienced it by hearing it from other people, seeing it from the movies and other external stimuli..our minds will always try to identify or match these raw emotions into something logical..these malevolent manifestations can sometimes be the work of our subconscious mind it is it's own way of explaining or putting an image to negative vibes, emotions and other ka ekekan!..and plus with a firm belief of the existence of the devil and other beings then it'll be validated by our conscious and subconscious nga si Satan jd diay to akong nakit-an sakong damgo or whatever place and time nmo nakta..
