the three voices refer to heather, claudia, and alessa
or supposedly........

The lyrics. I just love this song. ^_^

I am the first
A shadow at the end
of the hallway
I spin the carousel
The laughter recedes away
My finger on your lips
I stole something precious

I am the second
Alone in a faceless crowd
A human caught
in monochrome dreams
I scream to wake up
My voice drowns deep underground
Only the dead can hear me
see me

I am the third
A master
A sentinel of awakeness
I hold truth like a torch
Shadows flicker before me
Rapid eye follow the
Chain of thought
Until the silence ends

wow! sounds cool!!

Does anybody know who these three voices refer to?

This version is the best one of all.
This is truely my most favorite song of Silent Hill.
