Last night I was flicking through a book about everyday life and literature. Much of it was about Virginia Woolf and Joyce. What struck me were a few lines on Kafka, on his novella Metamorphosis. Now that was on the syllabus on one of the courses I taught so I thought I knew it quite well. But I didn't. What she mentioned was that the turning, the turning into a bug or giant insect is linked, not necessarily causally, but linked to the social. I did not remember that,  I imagined it as a much more psychically internal fantasy. But no it is not and further it could stand, I think, as a swirl story. So the image or symbol of being turned into vermin is both a function of stifling family life and the hideousness of life outside. 
So, one could argue that the whole piece, nightmare that it is, illustrates the swirl experience in a very graphic way. Here is a description from a New Yorker article on it:

The story’s protagonist, Gregor Samsa, is the quintessential Kafka anti-hero. He has worked himself to the point of utter exhaustion to pay off his parents’ debts, and his grotesque metamorphosis is the physical manifestation of his abasement.

Wikipedia is good too:

He reflects on how dreary life as a traveling salesman is. As he looks at the wall clock, he notices that he has overslept and missed his train for work. He ponders the consequences of this delay. Gregor becomes annoyed at how his boss never accepts excuses or explanations from any of his employees no matter how hard-working they are, displaying an apparent lack of trusting abilities.

So there it is. A sort of internal familial claustrophobia meeting an external anomie and producing or leading to a vermin state.

It is worth thinking about this further and thinking of other literary works that might illustrate our theme.
