A rent in the curtain...

A rent in the curtain...
Of nocturnal shadows and fading somnolent thoughts....

Light, folds,
grains, patterns, ...
overblown highlights,
contrasts, shadows...
darkness of night stealths
through a rent
in my bedroom curtain...
creeping penetrating fog
of distempered* darkness,
of bleary spreading tentacles
of shadows into nooks,
corners, crannies...
hardening into
the penumbra of opacity
through the cataract
of null light...
seconds... minutes.....
hours......
zzz zzz zzz...
soon... to usher in
the first new rays
of dawning light...
A new morn,
a new day beckons!

Why Distempered* darkness? (vexed, troubled, discontented, ill-humoured), my sentiments are clear from the poem above but aptly reflected in the following historical if reflective note:

Newton wrote a letter to John Locke in reply to one of his about the second edition of his book, (15 October 1693): "The last winter, by sleeping too often by my fire, I got an ill habit of sleeping; and a distemper, which this summer has been epidemical, put me farther out of order, so that when I wrote to you, I had not slept an hour a night for a fortnight together, and for five days together not a wink."
