The Running of the Bulls

I see my shadow stretched long on the wall,
Then I fall
And can see not at all.
I've been hit from behind by the
snake of the past
Whose teeth are of glass
And break off in my....
Ask me a question before I let go...
Of the rope that is holding....
My sense..
Tells me that there's something amiss
It chews at my being
So long, I've been dreaming
When I wake will I find that I've been left behind?
Or am I running ahead of the bulls in my mind?
