Green piece

My re-occurring dream,
I'll tell you what it means.
though i wish i could sing;
it still means everything to me.

i watch the shadows fall,
but i know the sun will rise,
i fill my hopes with turquoise
that i stole from your eyes.

i took the keys,
well, they were always mine.
black and white notes scattered the salty brine;
not a soul could stop me.

i'll tell you what it means,
i don't need to sing.
take me somewhere green,
and I'll select your piece/peace.
