“Exactly. There are all sorts of dream interpretations, Freud’s being the most notorious, but I have always believed they served a simple eliminatory function, and not much more—that dreams are the psyche’s way of taking a good dump every now and then. And that people who don’t dream—or don’t dream in a way they can often remember when they wake up—are mentally constipated in some way. After all, the only practical compensation for having a nightmare is waking up and realizing it was all just a dream.”
