The Unwritten Law

You turn on your side like you have to face North
Or else you can't sleep : the unwritten law
But how can you sleep with my heart so loud?
Like a scream in a jar, like the sound of a crowd
And way out at sea, the waves and the masts know that they've lost
That they're heading for rocks
But the captain's adrift in dreams of dry land
Of the view from the lighthouse, of my name in the sand
