When Raskolnikov awoke from this dream, a man was standing outside of his door. He welcomed himself in and introduced himself as Svidigaylov. This is the man that Dunya used to work for, but was fired because he fell in love with her (although she didn't love him back). He talked about his dead wife, and how he wanted to speak to Dunya. He also kept telling Raskolnikov that 'they'd become good frineds' and that 'he finds himself in Raskolnikov'. This makes Raskolnikov angry because Svidigaylov is not a good man. The man gives Raskolnikov a message to give to Dunya, which Raskolnikov is reluctant about at first, but then decides sto do so just to keep Svidigaylov away from Dunya. The quote "'They say that you drove Marfa Petrovna into her grave' is that so?' rudely interrupted Raskolnikov" deomnstrates situational irony. This is because Raskolnikov finds fault in Svidigaylov for his wife's death and holds it against him, even though he has killed two women himself. The conversation between the two of them end abruptly, since Raskolnikov had to meet his mother, sister, and her fiancee at dinner.
