I often spend time daydreaming & contemplating, that's how I come up with story ideas since I'm aspired to be a writer. When I don't do all that, I'll read any book (picking it up randomly from the piles in my room), babysit my nephew, do a research on anything that pops in my head: xenobiology, history of economy, aesthetics, climate changes, etc. (I have broad tastes!), or stream a movie. My favorite is usually an independent movie with a dash of fantasy or surreal element in it.
