Anna Karenina Part 2, Chapter 11 Summary

Just when you thought the tension couldn't go on any longer, Anna and Vronsky finally do the deed. There is no description of the event; we just jump right from those two lines of dots (representing a break of time and narrative) to the feelings of Vronsky and Anna after they've had sex.
Anna can't stop sobbing and her body is limp with shame. Vronsky is compared to a murderer and Anna to a murdered body. Anna now sees herself as a criminal, and Vronsky as the accomplice who has brought her to this guilt.
She tells Vronsky that she has nothing left now but him. She has been ushered into a new life, which fills her with horror, shame, and joy all at the same time.
She tells herself that she'll reflect on her physical relationship with Vronsky when she's calmer. That calm moment never comes, however, because Anna remains completely shocked by what she's done.
She has a recurring dream where she's married to both Alexis Karenin and Alexis Vronsky. In the dream, this seems like a totally normal situation, but then she wakes everything seems strange. It's really a nightmare more than a dream.
