“只在你脑海里”是一首模仿歌曲，由杰米·邓拉普创作，和瑞亚·史蒂文斯演唱。这首歌曲是模仿1994年小红莓乐队的歌曲《麻木不仁》（Zombie）。
当新来的在《南方公园：真理之杖》中到达南方公园小学后院的装卸仓库时，哥特帮所摆的播音机就会播放出这首歌曲。
歌词[]
All the love wrapped up in hate
In disguise as its lying in wait
The taste of your tears, bittersweet
As they fall down your cheek,
You feel nothing at all
You're alone, but you're never alone as you scream inside
Nobody hears you, nobody feels you, nobody sees you at all
Ahhh, ahhh, ahhh
It's all in your head
It's all in your head
It's all in your head
It's all in your head
In your head
In your head
