Poem By Me

This is a poem I wrote a few days ago.
Can you guess the subject from the content?

It flows unabated,unchecked,undammed,
To the inevitable sea of black.
Carrying too the flotsam and jetsam
The debris of so many dream strewn minds.

Through the falls and rapids ever swirling,
Bubbling,boiling around the bobbing hopes,
Straining and pushing with it's fierce intent
Of unrelentingly malicious fate.

Then the slowing,the drip drop arrival
At the edge of indiscrimination.
The pulling,the slipping,away from misunderstanding
The screaming,the silent inward screaming.

Now it has hold,there is no turning back
From the insatiable jaws of the void. Welcome friend!
