In a Dark Dark Room

The moon is full and white, and chill, this night, it cascades past my open window sill, and all the color fades to dark from light, a monochrome of gray which can't be stilled. The armoire's oblong shadow strays across the floor. I watch it from within my canopy bed. A nightmare gallops through an open door, a Pooka black as coal with eyes that bled. Its jaw agape and gore froths from his maw, as it slowly paws the cover from my bed, a scream freezes in my throat, a bird-like caw, he dips down for me to mount, and I am led. Upon this demon spawn, I scour the moor 'til dawn descends to belay this foul glamour.
