Creatures

In the shadows they lurk and in the light of the moon they hide, clock strikes 12 and in caves they dwell the streets they play scratching upon the graves. These ghastly ghouls or monsters do not play nice for your skin will feel like ice for screaming shouts from mouths the creatures come from the South, what are these monsters that lurk within shadows played upon the walls? Glasses break of alcohol bubbled inside and under the beds they wait to drag you under for their claws scratch floor and there's echoes haunting sounds coming from their horrid mouths, what do they eat? Why are they here? I guess one will not know until they search for graves down below.
