Who Am I

I see a man
But do not know his face
I do not know this man
But he will not go away
He looks like me
Could this all be just a dream 
Or am I just another reflection
In the mirror 
As his voice draws me nearer
The way that he speaks
This man does indeed 
So witty and wise
But does not say goodbye
Who is this man
And what draws him here
He brings with him all things
I once held dear 
He knows my name 
His is this same
If I am asleep  
(Oh God I know I am)
I will wake up and he will go away
And He will not come 
Back another day
I see a man 
But I do not know his face 
Him and I are not the same
We hold no interests 
And nothing in common 
Yet I still hear his voice
I hear him coming. 
I do not know this man
He will not go away 
He is witty he is wise 
But still will he not say goodbye
