How could it be?

I think I shouted something,
I wonder, I couldn't hear my voice,
It happened quickly, rapidly,
One scene piled upon the other,
I didn't see him coming, outside
Of time I thought I heard them
Running, were they coming or going,
I could never tell, trapped inside
This silent cell inside my head,
Trapped inside the moment, I saw
It rise, then quickly fall, black
Against black, a length of living
Night, I couldn't move, I could't
Seem to turn from the sight of
Blood leaking from his head, how
Could it be? Why? My mind somehow
Screamed out at the distant sky,
I couldn't shout, I couldn't
Move, I saw him hit him once again,
It isn't true, it's too insane,
How could it be? I found my voice,
Why? My question a noise that
Intruded on the shoking silence,
He turned his head toward me,
His eyes enraged, I felt him strike,
And I took the hit, but even as I
Bit my lip, even as the pain intruded,
The question drowned it out, how
Could it be?
