The flowing Sea

What do you think it's about? The flowing sea

The sea
she sings to me.
Through the foggy mist I listen to her.
Her songs hold no verse.
No chord set in stone.
She simply sings
what's in her heart.
I wish I could be
like the flowing sea.
I wish I could sing
about the joy and the sorrow
Locked away in my heart
But her heart flows
and mine
just beats.
She waves to me
and I wave back,
releasing the song
that's been sealed in my heart
for so long.
