Weirdest enemy in horror games?

Where is Steven, mommy? He can't play and I'm sad.
You mustn't ask, my darling - Steven has been bad.

Billy too, and Sally? Did they do something wrong?
I'm afraid it's true, child - all your friends are gone.

Beware of he who took them - he goes by many names.
The Bogeyman, the Shadowed One, but all are he, the same.

For every sin a child has, must be a punishment to bear.
Your friends are now beyond our reach; trapped deep within his lair.

And if they take what is not theirs, there can be no doubt.
He'll stretch their skin until it snaps, and all the blood drains out.

Remember to always behave, for sins he won't abide.
He wields a rusty, jagged blade, to cut out your insides.

The lying little children, with souls selfish and small.
Will find their wriggling tongues cut out, and nailed to his wall.

The bullies and their spiteful wrath will find torment as well.
Soon he will strike them where they stand and drag them into hell.

Child, you must obey your parents; do everything they say.
Little ones who do otherwise, he tortures in the flames.

Beatings cleanse the soul, they say, and that is what he'll do.
If you don't control your anger then you'll feel his anger too.

You are your brother's keeper, remember it always.
Or else, the Bogeyman will chain you underneath the waves.

And while good children live, bad ones cannot escape their fate.
For once you hear his screeching wail, it's already too late.

So do not cry aloud at night, stay hidden in your bed...
Or the Bogeyman from Silent Hill will come chop off your head.
