Three Voices

[Maria]

So... in the song Rain of Brain Petals with the three voices edited in.. who are they? Is there a commonly accepted idea of who's who or should I be asking who do you guys think they are.

just FYI:

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
