PRISONER'S DREAM

Last night as I lay sleeping, I dreamed a dream so fair;
I dreamed about my darling, a rose was in her hair;
I dreamed I left this prison, started in life anew;
She told me that she loved me, told me her love was true.

CHORUS: It was only a dream just a prisoner's dream;
As I lay on my cold prison bed;
My dreams of you can never come true;
Dear girl, I wish that I were dead.

I dreamed she called me darling, kissed me and held me tight;
I dreamed that we were married, dreamed of a starry night;
I dreamed about our children, playing around my knee;
They loved me, called me daddy, they thought the world of me. CHORUS

I dreamed a dream so lovely, heaven on earth it seemed;
My wife and little children came to me in that dream;
They threw their arms around me, I was their pride and joy;
My little wife said she loved me, I was her darling boy. CHORUS
