Svidrigailov's dreams

Dostoyevsky's dreamscapes before Svidrigailov’s suicide in Crime and Punishment are remarkable. First there is the nightmare of the girl of 14:

The coffin was covered with white silk and edged with a thick white frill; wreaths of flowers surrounded it on all sides. Among the flowers lay a girl in a white muslin dress, with her arms crossed and pressed on her bosom, as though carved out of marble. But her loose fair hair was wet; there was a wreath of roses on her head. The stern and already rigid profile of her face looked as though chiselled of marble too, and the smile on her pale lips was full of an immense unchildish misery and sorrowful appeal. Svidrigaïlov knew that girl; there was no holy image, no burning candle beside the coffin; no sound of prayers: the girl had drowned herself. She was only fourteen, but her heart was broken. And she had destroyed herself crushed by an insult that had appalled and amazed that childish soul, had smirched that angel purity with unmerited disgrace and torn from her a last scream of despair, unheeded and brutally disregarded, on a dark night in the cold and wet while the wind howled.

Then there is the nightmare of the five-year old girl. He finds her crying and shivering in a corner. He takes her to his room, undresses her, and tucks her up in a blanket. She falls asleep. Before leaving, he checks up on her again. This is what he sees:

The child was sleeping soundly, she had got warm under the blanket, and her pale cheeks were flushed. But strange to say that flush seemed brighter and coarser than the rosy cheeks of childhood. “It’s a flush of fever,” thought Svidrigaïlov. It was like the flush from drinking, as though she had been given a full glass to drink. Her crimson lips were hot and glowing; but what was this? He suddenly fancied that her long black eyelashes were quivering, as though the lids were opening and a sly crafty eye peeped out with an unchildlike wink, as though the little girl were not asleep, but pretending. Yes, it was so. Her lips parted in a smile. The corners of her mouth quivered, as though she were trying to control them. But now she quite gave up all effort, now it was a grin, a broad grin; there was something shameless, provocative in that quite unchildish face; it was depravity, it was the face of a harlot, the shameless face of a French harlot. Now both eyes opened wide; they turned a glowing, shameless glance upon him; they laughed, invited him.… There was something infinitely hideous and shocking in that laugh, in those eyes, in such nastiness in the face of a child. “What, at five years old?” Svidrigaïlov muttered in genuine horror. “What does it mean?” And now she turned to him, her little face all aglow, holding out her arms.… “Accursed child!” Svidrigaïlov cried, raising his hand to strike her, but at that moment he woke up.
