Blackbirds, curves and magpies, beyond their feathers, what do they represent?

While I listen to the voice  of the  blackbird
I look at your face
wondering
why why why
it's impossible to change past

I think of a thousand things
no clear thought stands out
from the crowd
that  stirs stirs stirs
in my mind
screaming words
that cover each others

everything could be so simple
like the games of a child
but you
have made me grave
of your dreams
and mine

we are dead and alive
under layers of time 
turned into  stones
over our heads

while I listen to the voice of the blackbird
singing singing singing
to the night 
to the  stars
that are still  what they are
inertia over inertia
like our life
