My friend "saw the light."

One afternoon was alone in my room when I heard a knock at the door. I answered and saw my friend. He asked if he could stay a few nights due to his girlfriend kicking him out. I said sure, mainly because I didn't mind as long as he bought his own food and things like that. After a night or two, I noticed something off about him. He would limp with his steps, would barely talk, and always stared out the window for at least an hour a day. After another two nights I finally confronted him about it. He stopped and slowly turned his head to me, then said something I will never forget. "I saw the light Gabe. The watcher has spoke to me and I know what I must do. I have been waiting for this moment where you spoke to me." I looked in confusion as he walked toward the kitchen, hunching his back and limping. Then he grabbed a knife and sprinted toward me. I jumped out of the way and grabbed my gun in self defense. I still don't know why he didn't grab my gun, but instead chose a knife. After he missed me, he turned and jumped at me, slamming into my coffee table. My finger hesitated against the trigger, but I couldn't bring myself to shoot someone I loved. Then he look up at me again. "You don't understand Gabe, the watcher knows all, he says I must kill you. The watcher has a reason, he always doe-" I cut him off and yelled: "WHO THE HELL IS THE WATCHER?" He dropped the knife and stared at the floor as if he had seen something. I took the opportunity to call the police, and soon he was taken away as I told them what happened. Last I heard he was put in an asylum, but I still am traumatized to this day. But recently, I have had dreams about an eye, speaking to me, telling me it knows all. I am starting to believe that this eye is the watcher, and I am desperately trying to get rid of these dreams. Doctors are no help, and my own family is telling me I might be going crazy. I think that I might be.
