I love the movie... but... am I the only one a bit confused about this? Is Ian her husband in the future? Did she really have Hannah? Were the visions of Hannah just visions? A glimpse in the future? I have seen it 3 times now and I have never got the idea that Hannah was never real. Geez, I am usually pretty good at this. If I can figure Interstellar out, this should be a breeze, lol. I do love this movie.
