It's like I'm paranoid...

Why does it feel like night today?
Something in here's not right today.
Why am I so uptight today?
Paranoia's all I got left
(...)
It's like I'm paranoid lookin' over my back
It's like a whirlwind inside of my head
It's like I can't stop what I'm hearing within
It's like the face inside is right beneath my skin
