"Something Happened."
It's one of Joseph Heller's novels. Most folks know Heller from "Catch-22" which is an amazing read, one of the all-time great novels, but "Something Happened" is also a brilliant, captivating, disturbing, & mind-bending book.
I think of it often, even now, so many years after reading it. It captures the vast uncertainty, and unknowingness of our moment to moment lives. There are big things going down, all the time, and we are swimming in a vast sea of possibilities. Something happened. We wander around wondering what.
Sometimes we just float along, going with the flow, then we look up and big portions of our lives have flashed by. What happened? Something happened.
