Hugo was originally a royalist, but later he turned to sympathize with and support the revolutionaries, which is well reflected in Les Miserables. Look at how he praises ABC's young people! Hugo also had a good impression on Napoleon, which can be seen from the ideological description of Marius and the large-scale description of the Battle of Waterloo.
About dreams, I don't think I need professional psychological knowledge to explain them. Les Miserables was completed in 186 1, while Feng Te founded the psychology laboratory in 1897, which marked the independence of psychology from philosophy (usually considered as the symbol of the birth of psychology), and Freud's Interpretation of Dreams was published in 1900 (the book "Interpretation of Dreams"). I don't think the previous psychology is systematic and scientific, and I have never heard of Hugo's research on psychology. Of course, Hugo's literary works are rich in fragments describing psychological activities, especially psychological struggles. It is impossible to say that he lacks understanding of human psychology.
I can't fully understand that dream, and I'm not a professional psychological researcher. The following personal views are for reference only:
From the context,
At this moment, he remembered that a few days ago, at the home of a dealer who bought second-hand goods, he saw an ancient clock on sale with such a name on it: Anthony alban of Romanville.
He feels cold. Made a fire. He didn't think of closing the window. At this time, he fell into terror again. He can't remember what he was thinking before midnight. He had a hard time and finally remembered it.
The above paragraphs take care of his dreams of "getting cold because of opening the window" and "Romanville" (actually a place name in the suburbs of Paris), and reality and dreams are mixed together. I think the dream here is fragmented, jumping, without logic and plot.
Everything is earthy, even the sky. . . Those people's faces are covered with dirt. . "Where are you going? Don't you know you're dead? "
This passage implies that he dreamed of being buried after death. Besides, I think he saw a desolate scene. There is a house with a garden, and no one cares about it in the city. It implies that he has been in the city since he got out of prison, and no one has accepted him.
As for the hairless man on horseback, I can't explain it. Whip refers to the abuse he suffered in prison?
I am very excited when I see someone asking a question about Les Miserables. . . Welcome to discuss.
