A Halloween Sonnet

I mentioned in a recent post that I've taken to writing sonnets in my spare moments. Here's another, timely one:

The dusky shadows lengthen and then fade
As evening brings a silver-crescent light.
The witches strut their ev'ning promenade
That signals to world the start of night.
The ghosts from long-forgotten graves arise
As hounds of heaven howl unto the moon.
Then, as the werewolves' wailing slowly dies,
A band of bogies plays a dancing tune.
Behind the grins of vampires: naught but glee
As skeletons mazurka by the wall,
The ogres polka dance, and ghouls bourée
In this, the joyous graveyard creatures' ball.
So do not fear the creatures you find dancing in the glen.
The monsters drifting through the night that you should fear are men.
