Trying To Grasp What You Already Let Go

I can feel it.
A shadow passes through me,
The ghost of something that was,
Something
That I can almost grasp,
But not quite.
If I listen quietly
To just the right tune,
I can bring it to the surface,
But I can never pull it above.
If I breathe in a certain scent,
I feel,
Rather,
I can almost feel,
What I had felt
In that time in my past
That I breathed
The same air.
I close my eyes
And revel in a
Fading past,
Sweet and memorable,
But sad sometimes
To even think of.
And as I reach out
To grab a piece of it,
And it slips of out my grasp,
It takes a little piece of me
With it.
But as I live in the moment,
I know there will be more
Fading memories.
I know that one day in the future,
My present will become my new past.
