Sometimes your eyes are heavy but you suddenly feel like someone's watching you. Sometimes, you're driving late at night and see something out of the corner of your eye. Fear has a way of creeping into your mind on the back of a single idea; that you're not alone. This is for when you're not sure if that person's been following you. This is for when you hear a single footstep outside your door in the dead of night. This is for when you're alone in a dark room.
