While audio might be a natural accompaniment to zonking off, screen-based culture is usually dissuaded by proponents of “sleep hygiene”. Still, as someone who regularly dozes off in front of the box, no matter how well-made and enjoyable the thing on it is, I can confirm that film and television can be of great assistance in conking out, too. And of course, “reading a few pages of a book before inevitably nodding off” has been a tried and trusted sleep aid for centuries.
