That's actually a really good thought, but I personally think you're perhaps being a bit too specific...I wouldn't go as far as to say that she wants a music box and that it's her father who's laughing like a maniac. I'd say it's more generally symbolic of her childhood...kind of as you described: full of innocence, hopes and dreams...and then the big bad adult world comes to get her. :O And that's the storminess and evil laughter. I think that can be meaningful for almost anyone though...I don't think you'd be a proper human if you hadn't had a similar feeling at one point or another.
GREAT JOB on pointing that out extepan. I never would have been able to rattle that off if you hadn't gotten my thinking started.
