Castle On The Cloud

Castle On A Cloud? Familiar much? Yes. It's from the musical play, Les Miserable. Generally, its main theme is DREAM. It clearly portraits the dream of a little girl named, Cosette. Cosette is a girl who never seen her parents and was raised by someone else since young. She was forced to do all kinds of house chores and not getting a chance to live like other kids at her age. 'There is a castle on a cloud', the castle refers to a place where she can possibly fulfil her dream, where she is loved and take care of.
Here's the lyrics of Castle On A Cloud:

[YOUNG COSETTE]
There is a castle on a cloud,
I like to go there in my sleep,
Aren't any floors for me to sweep,
Not in my castle on a cloud.

There is a room that's full of toys,
There are a hundred boys and girls,
Nobody shouts or talks too loud,
Not in my castle on a cloud.

There is a lady all in white,
Holds me and sings a lullaby,
She's nice to see and she's soft to touch,
She says "Cosette, I love you very much."

I know a place where no one's lost,
I know a place where no one cries,
Crying at all is not allowed,
Not in my castle on a cloud.

Oh help! I think I hear them now,
and I'm nowhere near finished sweeping and
scrubbing and polishing the floor.
Oh, it's her! It's Madame!

[MME. THENARDIER]
Now look who's here
The little madam herself!
Pretending once again she's been `so awfully good,'
Better not let me catch you slacking
Better not catch my eye!
Ten rotten francs your mother sends me
What is that going to buy?
Now take that pail
My little `Mademoiselle'
And go and draw some water from the well!

We should never have taken you in in the first place
How stupid the things that we do!
Like mother like daughter, the scum of the street.
Eponine, come my dear, Eponine, let me see you
You look very well in that new little blue hat
There's some little girls who know how to behave
And they know what to wear
And I'm saying thank heaven for that.

Still there Cosette?
Your tears will do you no good!
I told you fetch some water from the well in the wood!

[YOUNG COSETTE]
Please do not send me out alone
Not in the darkness on my own!

[MME. THENARDIER]
Enough of that, or I'll forget to be nice!
You heard me ask for something,
And I never ask twice!

This song truly inspired me to have faith in dream. Although Cossette is living in a difficult condition, she does not lose hope. She has big dream, she believes there is a castle on the cloud and her dream comes true when Jean comes to her. 

Live in the present is important, but dream makes your life wonderful. 
Dream as if you'll live forever, live as if you'll die tomorrow :)
