Requiem for Reality

Yesterday I was weak...I could not think.
My eyes were closed and I was set adrift in my own dreams...
I was after my tail, and when I caught and bit it, I was in pain
Tomorrow is a new day, isn't it?
Can't the sun shine again?
I was confused yesterday, cause I thought.
I thought about today, and what I would say if it came
And then today was yesterday, and I was chasing my tail again.
But tomorrow is a new day...A BRAND NEW DAY...Yesterday is gone...
I took yesterday out back,

and put a bullet in his heart
