Poetry From The Darkside

Evil monsters lurk within and they lurk to reap
They're in my mind and they're mine to keep  
They'll hide from light, but when darkness grows
They'll whisper incantations, in lines of prose
 
They're always there, but not well defined  
But the spells they cast, are to blow my mind
They're cloak and dagger, unreal, but stark
And so grotesque, they'll manifest the dark
 
They feed off nightmares, they feed off fear
I can hear their vile verses, for they are here
Their poetry from the darkside, is meant for me  
For in my direst reveries, there's a hanging tree
