The White Room

Why hello there,
welcome to my home.
Don't worry,
you're in no danger here.
My room is nice and padded,
I get all the luxuries.
Have you seen my jacket?
I can't find it anywhere!
Why am I in here you ask?
Well it's really quite simple.
It's for your own safety, of course!
I killed many,
with no mercy.
Blood spurted out of open wounds,
I didn't even care!
I loved the rush!
But then the men in the white coats came,
and took me away!
And now here we are
in my nice,
white,
room!
