Stuck for inspiration, I went to MoreWriting, to the Poetry group to see what prompts had been posted. Instead, I found this one, written by yours truly on a day when I had obviously slept badly. It was penned in 15 minutes for the flash, but I have spent much longer on it today, polishing it some more.

The murky backwaters

Dark thoughts meander through
The backwaters of my brain
As murderous plans are hatched
In blind alleys of disdain

Sharp splinters log-jam me
Pins prick at my tender skin
Another wound gapes wide
And I disappear within

I wait for the rainfall 
That will flush away this pain
Polish my murky soul
So I can start over again
