Why dream?!

I'm not a writer
being a poet
never was my dream
I dreamt one thing
Always believed
Will come true
Though reality once
ruined it..
That dream,
became a forgotten dream..
Never to be remembered..
That dream though left me
Survived some where
Held my promises to heart
Never followed me
But some where existed..
Ages passed..
That dream did last
Not with me though
In the distant past..
When I sleep
I hear agonising voices
Though not calling me
Yet I'm distracted..
Seems my dream is calling me..
Remembering me..
Taking me to that very distant past..
I find no way
I yearn in my sleep
There's unending longing
that breaks my sleep
Leaves no peace..
Awakening finds me tired..
Always thinking about that dream..
Unable to follow
With a deep hollow
I carry my days
An unending sorrow
Understanding, trust, love
were components of my once
Unfulfilled dream
My soul still screams
Who's responsible
My self or He
Who just watches and muses
At my misery..???
