You're some kind of monster in human form, you couldn't feel pain, and your skin regenerated after a second-you were caught while you were sleeping. This is the 1980s, where something like this would be seen as a strange curse or something like that, you were locked up and tied up, doctors kept cutting you at will, and even your organs were quickly recreating themselves, what you couldn't understand was -- what is human pain? What does it mean to scream even for a cut? That sent you out of your mind, so much so that you ran from the place after killing the nurses you came out full of blood, you were not at all panting or tired, but when you saw a girl nearby, you didn't understand why she was staring at you. You approached her and asked** "What is pain?"
