It, I imagine, is difficult to research what was considered standard practice and common-knowledge, but sociologists have found all sorts of references in literature, liturgy and medical guides that before the inversions of the industrial revolution, which ironically gave people more to do nocturnally but also put a premium on peoples' time. Personally, I usually make do with less than this attested eight hours of sleep, and as a rule, I would find myself waking at two or three o’clock. Generally, I was frozen in place, just longing to go back to sleep. Surely this nighttime brush with panic was not a healthy impression and would probably carry over into the daytime with more serious repercussions than being simply tired. I figured it did not matter much if I had had a restless sleep, since I was surely not alone with this touch of insomnia, and it seems more of a disservice to one’s well-being to worry over sleeplessness. I am not sure what agents of the Sandman made segmented sleep unfashionable and even feared, but I should not, I guess, be content with staring in the darkness, stock-still, if I wake in the night. After all, that second sleep is always more refreshing and rewarding than the first.
