can anybody tell me the exact plot of MULHOLLAND DRIVE

Hi....I am wondering any body has understood the movie "Mulholland Dr." According to critics, it is the best noir-psychological thriller.
the plot is :- A bright-eyed young actress travels to Hollywood, only to be ensnared in a dark conspiracy involving a woman who was nearly murdered, and now has amnesia because of a car crash. Eventually, both women are pulled into a psychotic illusion involving a dangerous blue box, a director named Adam Kesher, and the mysterious night club Silencio.

It is with such a non-linear plot... you can't see such a non-linearity in any movie....and the scenes fluctuate between dreams and real world. Till now, nobody understood the film completely. Director David Lynch in one interview gave some clues ( points) to understand this thriller. If any body watched and understood completely...I salute him :)
