The article analyzes the dream that Leo Tolstoy had before "leaving" Yasnaya Polyana. Tolstoy wrote down this dream and included it in the list of his prospective plots. On one hand, the dream was prompted by Tolstoy's reading of Dostoevsky's novel The Brothers Karamazov, and on the other by the personality of his deceased intimate friend Nikolas Strakhov. The reconstruction of this prospective plots offered in the article is based on our recent discovery that one of the characters of the The Brothers Karamazov, Rakitin, is a cryptographic pamphlet on Strakhov.
