Paradise by Coldplay

This song has been one of my favourite songs since the day I heard it. I literally abused this song, before getting tired of it. The meaning, the Genre - everything is so right with this song. Let's play a game.
I will write the lyrics of this beautiful song and you will explain what you understand by it. Are you ready?

"Paradise"

When she was just a girl
She expected the world
But it flew away from her reach
So she ran away in her sleep
And dreamed of
Para-para-paradise,
Para-para-paradise,
Para-para-paradise
Every time she closed her eyes

When she was just a girl
She expected the world
But it flew away from her reach
And the bullets catch in her teeth
Life goes on, it gets so heavy
The wheel breaks the butterfly
Every tear a waterfall
In the night, the stormy night, she'd close her eyes
In the night, the stormy night, away she'd fly
And dream of

Para-para-paradise
Para-para-paradise
Para-para-paradise

And so lying underneath those stormy skies
She'd say, "Oh, oh-oh-oh-oh, I know the sun must set to rise."
