Just like most people in this world, I love to stimulate myself. But unlike those emo people who like to cut and bleed themselves as stimulation, I guess I have other things in mind (and it's not as sexually dirty as you are thinking right now). Nothing makes me more agitated or excited as scary stuff. I love ghost stories and zombie apocalyptic types of movies.
But what freaks me out the most is exorcism movies--not only are they scary as hell in terms of visuals, but they are also psychologically disturbing. What's more scarier than a devil who can possess you or other people against your will, right? And you don't even know how to fight it, too! Unlike zombie which die eventually when the brain gets bashed or blown up, the devil is powerful, albeit limitless. No walls, no gates can hold him. Worldly weapons don't work against him. Only God can conquer him.
