Distinguishing the artistic chronotope of literature or more broadly discourse from the lived space-time of reception, Bakhtin describes a dialogic movement between the two: The work and the world represented in it enter the real world and enrich it, and the real world enters the work and its world as part of the process of its creation, as well as part of its subsequent life, in a continual renewing of the work through the creative perception of listeners and readers.
