Lucid Dream related movies? If so I wanted to hear anyone's thoughts on the movie Vanilla Sky. Also wanted to ask if anyone has seen the movie Waking Life and if so if it is worth seeing. Also if anyone knows of any other movies about or pertaining to Lucid Dreaming.

In reference to Vanilla Sky I am a bit confused about the ending. He payed for a lucid dream while in chrogeneic freezing however he was not in a lucid dream till the very end because he didn't realize he was dreaming till then. Now the way I understood it was that there was a glitch that kept him from realizing he was dreaming. Is that what it was? Or did the writers just not understand the concept of lucid dreaming?

At any rate if somone else has posted about this which is likely the case let me know where.
Thanks.
