Treading Water

I can feel this river boat,
Sinkin' as I cross this moat.
Headed for this castle of Death,
Praying for one last breath.
I reach the riverside,
With my life not far behind.
Treading these waters...
Swimming towards eternity.
Swaying side to side,
My life before my eyes.
Flashing before it's time,
For me to say goodbye.
