As for Audrey, I've seen some complex theories, but for me, the simplest explanation works best. She was in a coma for 25 years, including her pregnancy. The initial scenes we see are her unconscious visions as she struggles to wake up. Her final moment is the shock of waking up to realize she's slept through 25 years of her life.
