Solitude - (A New Piece For My Zombie Epic)

This is going to be part of my zombie epic (if I ever get around to finishing it). Unfortunately, I am unsure which character is speaking to me with this one. I am sure I will figure it out in time...

It haunts me in times of solitude
A vague whisper of a dream I can almost remember
The lingering warmth of a forgotten touch
I sense it there, in the darkness
In the quiet moments of times I can barely recall
Resting on the limits of my reason
It calls to me, urging me to cry out
Only to have my voice echo into nothingness
It is a history that was written in stone ages ago
And every figure of it has faded away
To leave me here to live in the shadow of a wraith
A vision of what was and a lost wish of what may be
I know it, and I know it is there
It waits for me to discover it once more
To unearth the secrets it holds and find myself
Because without it I am but an undefined impression of possibilities
It becomes me as I have always been a part of it
A promise that has existed since the dawn of thought
A gift inherent in the very fabric of the soul
But it hangs shrouded by the hopes of man
Concealed in ghostly images of all that it should have been
Here in the silence I hear it through the veil of time
And its words reverberate in the core of me
I quiver, though in fear or anticipation I cannot be sure
All my knowledge of it is an amorphous conglomeration of confusion
To reach out, to grasp it, to understand
But it is the phantom that lurks over my shoulder
That dream I can almost touch
It visits the edge of my memories and lines them with silver
It comes to me while I am alone with the past
And its vanishing countenance stays with me
