The Windows on the Worlds, Behind

There are,
Two worlds;
Behind.

One is circumfactual;
Simply practical…
The other is teasing;
Not always pleasing,
You understand?

Look –
Your rear view mirror!
All that was familiar,
Is shifting sand.
A shimmering, rippling reflection
As from a glassy lake.

Observe the impalpable movement:
A fleeting, darting;
Beneath.
And so… to grasp sight.
To capture that glancing look.
To perceive ever deeper into those eyes;
Behind.
