Villian of the Night

A poem in one of my "trio sets".

Creeping about the woods
Under the night's navy blue
A person in dark clothing
Coming after you.
While you sleep so heavily
In your comfy bed
Approach does the menace
And in seconds you're dead.
So keep a watchful eye
For tonight may be your last.
Your sleep could be made eternal
By that fatal slash.
Be calm, don't scream
do not show your fright
For you may alert the attention
Of the villian of the night.
