As someone who has experimented a lot with lucid dreaming, brainwave entrainment and the like - I wholeheartedly agree. This is - behind the disguise of an entertaining action flick - a really great movie, playing on our concepts of reality, and showing us a few of the possibilities that are not so much 'fiction' anymore. A lot of the technology and approaches in the movie are actually being worked on or already available.

Voted (bit late, sorry xD) & followed.
