The true nightmare.

I was a human, but he was a vampire,To Every evil soul, he was like a fire.
I wanted to escape,But can't avoid my inside's desire.
To every love story, there is a villain,To every glory, there is an end.
& to every thrust, there is blood.
I had to kill that thrust, like it was a dare,But now I can't differentiate between,
What is true and what is Nightmare!
