To Mourn Oneself

I wonder if conciousness erodes overtime
Every piece of my body has been replaced
My body, my mind-why not that?
Death is darkness and there falls every memory
Is the child I used to be dead?
And when did he die replaced by me?
He dreamt of the day his world begins
I dream of the day world ends
Is he dead?
If so I want to be that little boy
Quietly sleeping, endlessly dreaming
Of nothing at all
