"It's at night, when perhaps we should be dreaming, that the mind is most clear, that we are most able to hold all our life in the palm of our skull. I don't know if anyone has ever pointed out that great attraction of insomnia before, but it is so; the night seems to release a little more of our vast backward inheritance of instincts and feelings; as with the dawn, a little honey is allowed to ooze between the lips of the sandwich, a little of the stuff of dreams to drip into the waking mind. I wish I believed, as J. B. Priestley did, that consciousness continues after disembodiment or death, not forever, but for a long while. Three score years and ten is such a stingy ration of time, when there is so much time around. Perhaps that's why some of us are insomniacs; night is so precious that it would be pusillanimous to sleep all through it! A 'bad night' is not always a bad thing." ~ Brian W. Aldiss
