Four star mary - "Pain" lyrics:

Feeling I've been lost for years
You can never understand me
Unless you've seen those tears
But you never get to sleep when I'm away
I don't mind the deeper that you lay
Out of time
Pain
I can't sleep
Pain
I can't sleep
Running, running from those days
There's another one inside me
Guess I've gone insane
But you always run away
When I come around
I don't mind the day
I'll track you down
Run you down
Pain
I can't sleep
Pain
I can't sleep
Don't stop
Don't talk
Do not (fuck) with me
Don't stop
Don't talk
Do not **** with me
Loaded, loaded up this gun
There's a killer in me
Hoping, hope that you're the one
But you always run away
When I come around
I don't mind the day
I'll track you down
And terrify
Pain
I can't sleep
Pain
I can't sleep
Pain
I can't sleep

Lyrics to the song in Buffy's prophetic dream during the episode Hush (Season 4 Episode 10)

Can't even shout
Can't even cry
The gentlemen are coming by
Looking in windows
Knocking on doors
They need to take seven
And they might take yours
Can't call to mum
Can't say a word
You're gonna die screaming
But you won't be heard

The song clues the Scooby gang in on what the gentlemen do:
They need to take seven
And they might take yours
Refers to the seven hearts they need to collect
You're gonna die screaming
But you won't be heard
Refers the fact that the Gentlemen take away their voices
