Thats a great list. What about..
- POMO texts like to play games with ontological levels, flickering between different layers of 'reality' and representation like Ros & Guil Are Dead, Purple Rose Of Cairo, Will Self's short stories, Pynchon's Vineland.
-Often use 'ontological flicker' - a term of Brian McHale's, about switching between levels to create a kind of vertigo.
-Ontology: the branch of philosophy that studies what is. It includes defining categories like reality, illusion, etc.
Mise en abyme
-Literally 'thrown into the abyss' the phrase, from the French, to explain, in heraldry, where shields are inside shields inside shields. Like the effect created by mirrors in a department store, you get a vertiginous disappearance into the horizon and lose sense of perspective. Such Chinese boxes, or Russian Dolls effect, can be seen in Paul Auster's New York trilogy, or even, in part, FLW.
