Vampires

Vampires... What are they?
Beasts? creatures? Undead?
I say they are awesome, even after they fed.
While everybody is sleeping in bed,
We go out and feed, off of humans,
And turn them into one like us,
And the rest run towards the midnight bus.
We eat off the unlucky walkers in dark,
Because we have to keep us secret and dont spark.
So we don't get caught,
We have never fought.
We are the creatures of the night,
And when people see us, they quake in fright.
Vampires...Who are they?
One is me.
