Looking for similar books to all of: Notes from the underground, The Metamorphosis and A moveable feast

Hi all,

I recently got much more into reading and have finished the three in the title within the past month. I am looking for recommendations similar to those.

The kind of things I like in a book:

Existentialism

Truly bizarre (think the plot to the metamorphosis)

Exploration of human psyche, preferably the darker side (notes from the underground)

In the moveable feast, I really enjoyed Hemingway meeting all of the various writers/artists/characters in Paris. I particularly enjoy the ‘vibe’ of Paris, and enjoy stories centred around it. Particularly Paris in the 1920s, 1940s and any time period before that. Not so much modern Paris.

Thank you!
