Suggest me a book that feels like fever dreams

I'm totally hooked on 'Fight Club' by Chuck Palahniuk, and I just wrapped up 'The Metamorphosis' by Kafka. Kinda fell in love with that one too, weirdly enough.

I realized both books give me this wild 'fever dream' vibe that I can't get enough of. Got any recommendations for something with that same feel? Preferably a shorter read. Thanks!
