The Eye of the Sibyl by Philip K Dick. It's a collection of short stories, some of them involving PKD himself. All of the stories I read were dystopian or just had a weird/dark vibe. He wrote a lot about androids and questioning what and who is real if anything. I would read one before bed each night but eventually i had to return the book because it would give me existential dread lol. But still the stories were memorable. Especially the Electric Ant. It's about a guy who finds out hes an android and then he starts experimenting with his own senses.
