Night shift dream: the elevator keeps going up past the roof

I dreamed I was working a night shift in a hospital corridor, and the elevator kept going up past the roof, opening onto a dark field of grass that smelled like rain. I kept telling patients I'd be right back, but I never got to them. There was no panic, just a dull feeling that I was failing by exploring instead of staying in my lane. Woke up annoyed at the universe's metaphors, then checked the window: actually raining here too.
