Media that made you question the established notion of what's real?
At the risk of sounding like a reddit post, I'm looking for TV shows/movies/books that made you ponder whether any of it is real, made you feel like exploring unexplained mysteries, maybe even inspired you to study physics with mathematical rigour.
What I've liked so far:
TV shows: Dark, Devs, Fringe, 12 Monkeys
Movies: The Prestige, Coherence, Shutter Island, Predestination, Memento, Triangle, Primer, Interstellar
Books: One, two, three, ...infinity - Gamow
