Most readers seem to expect fiction to have a single, stable truth. If it is a realist story, it must of course be “realistic” and have a certain objective truth. If it is a fantasy or science fiction story, readers expect a coherent world and consistent rules. Part of the genius of Kafka is his willingness to ignore those concerns. His stories are not worried about logical consistency or world-building, but in emotional and psychic power. They are peppered with moments, such as this passage, where the reality of the story crumbles around it and rebuilds itself with unexpected logic into something new.
