ophelia's madness

pgs. 215 to 219--
this scene is probably my favourite scene in hamlet. it's all over the place; first crazy laertes enters, threatening claudius. then claudius belittles him completely and basically eggs him on by cooling down like an iceberg. then gertrude gets all fussy when ophelia bursts in....
it's really ophelia's madness that makes the scene, though. i keep going back and forth on whether or not there's any connection to what she's saying and her brain, if any of it makes sense w/ regards to the circumstances, or if she's just pulling a bunch of.. stuff out of thin air. maybe she has gone utterly insane, or she's pulling a hamlet, with a very legit excuse, just so she can make a big load of metaphors and hope to god that someone will understand them. for instance, the moment when she turns to the king (it was very pointed in branagh's version) and says, "lord, we know what we are, but know not what we may be." then again, she goes on to talk about st. valentine's day.. it's hard to tell if she's making it ALL up. or just some of it. or none at all.
personally i think it's a combo. those instances where she clearly has a purpose and a meaning to the words are too often in the scene to discount. especially the passage about hamlet not coming to her bed... which was very visually referenced to sex, thanks to branagh's version... and also the flowers on her father's deathbed.
