This is me

At any given moment
I could be lost
in a different world.
Where my mind goes,
not even I could say.

In the evening rain
is where you will see me hide,
but the breath of my soul
is all you will find.

Who am I?
Watch my sigh.
What do I want?
Feel my tears.
What do I live for?
To learn,
to laugh,
to live.

How will you hear me?
When I speak of ideas you never heard.
How will you know that it is me that you met?
By the smile that I have put in your weary face.
