Insane lyrics - Mercyful Fate song

I see little demons, are they in my head?
I see little demons, fightin in my bed
Why did I go insane? Oh doctor kill the pain
Screams in the night, I hear another one died
Was it number 9, or was it me who cried
Why did I go insane? Oh doctor kill the pain
When I look in the mirror, my mind goes blank
My brain is burning up, Insanity...
When I look in the mirror, my mind is, Dead
Is it me on the other side?
I saw the look on your face, the night they took me away
Not a tear, not a trace, just stood there waving goodbye
Dead roses in my room, a love that died too soon
When I look in the mirror, my mind goes blank
My brain is burning up, Insanity...
When I look in the mirror, my mind is, Dead
Sanity turned Insane, I hange myself in a picture frame
I'm so tired, let me sleep
I'm counting demons...
Oh doctor kill the pain, oh doctor kill the pain
