Fyodor Dostoevsky,
The Brothers Karamazov — Part IV, Book XI, Chapter 9
(1880)
“ The anecdote is so characteristic that I couldn't have taken it from anywhere. I thought I'd forgotten it... but I've unconsciously recalled it- I recalled it myself- it was not you telling it! Thousands of things are unconsciously remembered like that even when people are being taken to execution... it's come back to me in a dream. You are that dream! You are a dream, not a living creature!""From the vehemence with which you deny my existence," laughed the gentleman, "I am convinced that you believe in me.""Not in the slightest! I haven't a hundredth part of a grain of faith in you!" ”
