I dreamed I was the last person on a hospital rooftop

It was raining, but not wet — more like static falling through the air. The ICU windows were all dark, but I could hear the beeps from below, faint and slow. No one else was there, just me and the sky, and the sound of someone saying 'I'm fine' over and over, like a loop that never ends. I kept thinking: if no one comes to check, does it matter? Then I woke up and remembered — I already know the answer.
