Quotes: Journey to the Center of the Mind

You lock the door
And throw away the key
There's someone in my head but it's not me
Pink Floyd, "Brain Damage" - The Dark Side of the Moon.

We're going deep into your mind!
Your psyche will unwind
Was there a monster 'neath your bed?
A fear of moldy bread?
Or just a giant floating baby head?
Going deep into your mind!
Phineas and Ferb,"Going Deep Into Your Mind"

Ooh! Ooh! There's a party in my brain and you're all invited!
