I don’t know where gwern went in the Midwest, but in northern parts of the country (like Minnesota, or Seattle) the extreme shortness of the days in winter can produce that effect. When you wake up when it’s dark, spend all day indoors, and the sun has set before you leave work, you can get the same feeling of days blending into one another, because you never notice the sun rise or set.
