Dark side

My dark side is anything but harmless,
A wild horse with no harness.
His eyes fill me with fear,
For he knows what I hold dear.

His horns extend outward,
His presence will leave you with no word.
His skin burnt like charcoal,
He tortures me with no goal.

His claws slash my face,
He is my creation,there is no saving grace.
I opened my eyes,the nightmare reached its conclusion,
Tears start to flow as I realized it was no illusion.
