What does the ending mean? (SPOILERS!)
After yesterday's screening at Seattle International Film Festival, people leaving the theater all seemed to have a different explanation for the ending.
My interpretation was a twist on the idea that people's lives "flash before their eyes" when they think they're about to die. But instead of seeing her life up to the point of the car crash, she sees the life ahead of her if she survives.
Another one I heard was that it was a simple case of the film showing what might have been. (That's in contrast to my idea, that the character was seeing what might have been for herself.)
Less analytical thoughts suggested that maybe it was just a bunch of crap.
