Nightmare Comes By

I can feel something not human staring at me
The air move still, nature freeze, terrified
As the full moon rise, nightmare comes by
Nightmare comes by
I've changed myself to a sickening creature
Devoured by human blood thirst
I am shaped to kill
I shred the flesh
I spread my plague
To increase my pack
Now night had ended
I return to my true self
Unaware to what has happened
Cycle will start anew day
Until death
