Quotes / Sanity Slippage Song

We all deserve to die,
Even you, Mrs Lovett, even I,
For the lives of the wicked should be made brief,
For the rest of us death will be a relief,
We all deserve to die!
"This kettle is boiling over
I think I'm a banana tree"
-Queen, I'm Going Slightly Mad

"No, I've never been insane
Ah, what's the game?"
I believe I'm dying!"
-Supertramp, Asylum

And parasites are eating at my brain,
And nothing is the way it was before,
A pack o' wolves is howling at my door,
Dead men's dreams,
Filled with screaming pain,
Hurling me to mad extremes
In a world that's gone insane.
-Jekyll & Hyde

Rocked, silent, in a soft lullaby
Panic stirring me, awakened by a ringing phone in time
Where and when would I see her?
Crazy were the words that scribbled out your mouth
I stuttered, replacing your face to those words,
Where and when would I kill her?
— "The Camper Velourium II: Backend of Forever," Coheed and Cambria

Remember when you ran away
And I got on my knees and
Begged you not to leave because
I'd go berserk
— "They're Coming To Take Me Away Ha Ha," Napoleon XIV

The lunatic is in my head
The lunatic is in my head
You raise the blade, you make the change
You re-arrange me 'till I'm sane
You lock the door
And throw away the key
There's someone in my head but it's not me.
Brain Damage, Pink Floyd, from the album The Dark Side of the Moon.

Unusual and bizarre,
I have gone much too far.
Not my fault my thoughts are out of the norm
I am not right in the head,
Nowhere near a full deck,
Maybe my parade is led slightly off-beat?
— "Personal Demons," Rufus Rex, from the album Dead Beat.

Marceline, I can feel myself slipping away
I can't remember what [the crown] made me say...
—From the song "Remember You", Adventure Time
