I don't get it- Spoilers

I think everyone is looking at this movie too literally. I could be wrong but I think everything was symbolic and not meant to be taken at face value. It reminded me of "the girl in the swing" or some other of those artsy movies. I think Nora was told she had to quit drinking and from then on it was more of a symbolic journey about why she had started drinking. What she was hiding from. Her mother being blown up by a car bomb, having to live with her uncle and grandma getting pregnant at 16 or however old she was and having to have an abortion. I even felt there was an incestuous overtone when the Druid witch began to take on her features and the uncle leaned in to kiss her and thats when she slashed his throat. I think the whole movie was a purging of the demons that caused her to want to drink. The Druid witch represented her ancestry, things inside her she felt were beyond her control and then after she'd started to take on her image and they were melding into one person the 'witch' was displaying all these behaviors that were very basic and extreme. Ultimately instead of being taken over and dragged under by the 'witch' Nora made a decision to change because her son was in danger and that was the one thing that mattered to her, broke her alcoholic haze. So rather than be overcome by these circumstances in her life she "killed" herself and was ultimately free of the demons and the person she had been, finally. Remember the little girl narrator said when Nora's husband looked into her eyes he could see a clarity finally. And that they started over from that moment which I believe is because she had let go of all the things that she had been allowing to destroy herself and her family. I admit the gardener was a little obtuse but I think it can at least be explained if you're looking at the movie as symbolic instead of actual. The thing that really solidified the symbolic theory for me was when the she was in the basement with her grandma looking for her son and Nora told her she didn't think she could do it and her grandmother gave her the potato carving and told her it belonged to her mother and she knew she was strong and could do this and the scene sped up through the hall and up the stairs and suddenly they were on the beach. That felt like a dream sequence kind of film technique. I think the whole thing in the library with the records killing the ex boyfriend was all just the symbolic destruction of memories. I know people will argue and say that I'm giving the film too much credit but thats my interpretation of the movie. Anyway I hope that helps a bit.
