at once; there is a sort of indefinable something about it
which is not exactly an insult, and yet is an insolence;
and one which is hard to bear, too. I lay there fretting
over this injury, and trying to go to sleep; but the harder
I tried, the wider awake I grew. I got to feeling very lonely
in the dark, with no company but an undigested dinner.
My mind got a start by and by, and began to consider the
beginning of every subject which has ever been thought of;
but it never went further than the beginning; it was touch
and go; it fled from topic to topic with a frantic speed.
At the end of an hour my head was in a perfect whirl and I
was dead tired, fagged out.

The fatigue was so great that it presently began to make some
head against the nervous excitement; while imagining myself
wide awake, I would really doze into momentary unconsciousness,
and come suddenly out of it with a physical jerk which nearly
wrenched my joints apart--the delusion of the instant
being that I was tumbling backward over a precipice.
After I had fallen over eight or nine precipices and thus
found out that one half of my brain had been asleep eight
or nine times without the wide-awake, hard-working other
half suspecting it, the periodical unconsciousnesses
began to extend their spell gradually over more of my
brain-territory, and at last I sank into a drowse which
grew deeper and deeper and was doubtless just on the very
point of being a solid, blessed dreamless stupor, when--what was
that?

My dulled faculties dragged themselves partly back to life
