As I´m currently writing an essay on the occurences of puns and word-playing in dreams, I´ve illustrated two examples from my own dream experiences. Both examples, that were seen as well as heard, were dreamed as pictures that I feel were derived from verbal puns or word-play.
This image and its title came to me in a dream after having read a good book titled The Methodology. Around the "Frankensteinway" at the bottom at left I have also drawn the components of this invention, which read as a chain of associations around replicating processes: a Steinway piano, Frankenstein´s monster, a Komodo dragon (recently known for being able to reproduce parthenogenetically) and the greek Parthenon temple.
The word Frankensteinway is an example of what Max Ernst called a "phallustrade", which, according to the surrealist dictionary is defined as "an alchemical product, composed of the following elements: autostrade, balustrade and a certain quantity of phallus. A phallustrade is a verbal collage."
This image and its title is a pun trying to invert "nuclear family" by opposition; the earth or mud that stains the laundry seem to allude both to a geological crust and to the gritty crust-punk lifestyle (crust is perhaps an onomatopoetical name for how this style of punk music sounds, but the name could in turn also have been chosen as a pun by opposition on the hardcore influence upon the genre.)
The commentary section below is the right place to gather more examples of word-playing and verbal or visual puns in dreams.
