Who wrote this poem?

While you were sleeping I felt your heart beating.
While you were sleeping in my head love was repeating.
While you were sleeping all I could do was smile.
While you were sleeping I watched you for a while.
While you were sleeping I always held your hand.
While you were sleeping I knew where my heart would land.
While you were sleeping you would hold me near.
While you were sleeping I would cry all my tears.
While you were sleeping from you I knew I wouldn't part.
While you were sleeping I gave to you my heart.
