There is a hole in my world.
It is not black; it is not dense.
It is not bright; it is not light.
It is not a portal, nor a fence.

It is not something missing.
What is unseen, what is unknown,
What is unnoticed, what is fogged...
What is covered over and not shown...

What is not seen, is still there.
It's just shadowed; it's just behind.
It's just hidden; it's just obscured.
It's just not in full view of the mind.
