It's being mentioned a lot that most parts of the movie must have been a dream. And I'm inclined to agree but... it's a David Lynch film we are talking about... So... there must be more than just the obvious... and I'm pretty sure that it was made in a way that there can be no final answer to all the questions...
He once said that he's into horror originating in the unknown so he probably just wants some things to stay unanswered... some things to not make sense, to leave loose ends behind, to keep people guessing...
Yes, David Lynch's cinema leaves a big part to the viewer's interpretation. What I stated was just my own perception of the movie, even if there are some points a lot of cinephiles agree with. There will always be unanswered questions and you'd always have to figure out the meaning of some details by yourself. Again, rather than trying to understand it, I believe one should in the first place contemplate and feel the concerned Lynch's movie, and in this case, Mulholland Drive.
And there's also another important fact about that movie that a lot of folks seem to forget about...
Go ahead.
But… before I add my two cents about Mulholland Drive here, I have two more questions for you:
What does the box represent for you?
And care to explain further how “love triumphed over hatred” exactly...?
That's just me being curious again ^^
The blue box symbolically represents Diane's demise, more precisely when she opens it. When Diane asks Joe about the utility of the key, he answers by laughing, its only purpose is to confirm that the contract has been executed. Which is why it's empty. Only remains the void Camilla vanished into, and where Diana is going to disappear too.
This box is probably one of the details whose signification is nearly entirely left to our interpretation; I've read that it could also be Diana real life's jewel box, which makes sense since, in psychoanalysis, a jewel box, and on more globale scale any "containing" object symbolizes female.
As for the "love triumphed over hatred", it's the feeling the end gave me off. Like I said, even if Diana went insane and caused Camilla's death, her absence still hurts her more than her betrayal, and since she can't stand the death of her beloved, she decided to follow her, and thus to kill herself. Diana's love for Camille is too strong she can't even run away from her guilt in her dream, that's how much she loves her. So, even if it's like a tragedy, her love remains stronger than her hatred. And that's why I consider her suicide as her salvation and as- if not a happy one, a really beautiful ending.
So, it's your turn to add yout two-cents now :P
