It's late. You're tired from a long day and decide to sleep; rest your mind. You change into something comfortable and slip into your bed. Of course, you don't check under the bed or in your closet. Monsters aren't real; they haven't been since you were younger.
Your eyes begin to close, slowly but surely, as you drift to sleep. Every internal guard you may have built around your mind is retracting; everything you want kept out is silently creeping in as well as anything you want kept in is gradually oozing out. Your wonders, fears, hopes, despairs, displayed. You're vulnerable. Subconsciously realizing this, you wrap yourself in the blanket, hoping for some kind of protection. It won't help though.
Your breathing continues at a steady pace, slightly faster than your breathing when awake. You shift in preparation of the long hours ahead. Silence.
Your mind, still slightly aware, registers the light tapping at the window as a branch blown by the wind. The quiet creak in the hallway is a product of the house's old age. Every small sound has a reasonable explanation, so you finally sleep, letting all consciousness slip away.
Although the tapping at the window has vanished, the hushed creaking in the hallway continues. A slow but confident pace. The sound seems to reach your door then ceases. The door is eased open slightly, allowing a sliver of darkness, somehow darker than a shadow, creep in. It glides over the floor stopping at the foot of your bed, then begins to grow. At eight feet tall, he gets a good view of you while you sleep. Extending his arm to hover over your form, a long, slender finger gently slides down your skin, making you shiver in your sleep.
He crawls over to the side of your bed, facing you. This seems to be one of those nights he wants to plant a nightmare in the mind of a dreamer, so he decides he will settle for yours. Looking at you, he can see everything you love or fear. All the things you cherish. He slips a small amount of Darkness into you, which then contorts your images of happiness into something horrid. He watches as you begin to sweat and writhe from fear.
As his sunken eyes take in your frightened form, his thin, pale lips lift in a smile. His chalky features seem to be alive from the bliss. He simply adores his work. He doesn't discriminate his victims; with children, they awake screaming, alarming their parents who assure them monsters aren't real. In teens, they always want to display that they have no fear, yet when they've see him, they almost go insane trying to erase the thought of him. Adults, when with a partner, will tell the other of their encounter then try to hold them closer as a form of protection. When alone, adults will experience more fear, having no one to turn to, so most of the time, they stay awake.
There is one thing he loves though; their screams. When they scream, they open an entryway to their bodies. He wouldn't enter anyone of a family though. Those who have no one, those who truly are alone are the only ones he'll take. When they scream, he will enter them and lead them away. Once taken, they don't return.
In his dwelling, those he's taken are locked away. They serve only as victims to his frightening actions, whether they will witness him twisting his own bones to form himself into another creature or if they will stare into his depthless eyes seeing images of people burning, being ripped apart, tortured, paralyzed from fear.
He usually doesn't kill them unless he grows bored of their shrieks. When he does, he slaughters them and makes the remaining victims watch as he covers himself in the blood, then smiles as the warm liquid drips off his form, his chin. Their screams are new, more blood-curdling as they see the fresh image of horror.
He doesn't see himself as a monster, merely a creature who gains delight from doing horrible things, but it's always the same routine. Centuries of doing the same things gets old eventually. Lately, he's wondered if it would be so bad to take anyone of his choosing, whether part of a family or not. After all, who will catch him? Or even suspect him?
There's no way to stop him from coming for he is always there, watching, waiting for the right time to meet you. No matter what precautions you take, he will find you, if he really wants to. Hopefully, you can remember that no matter what, don't scream.
