Waking Life is a great suggestion, too, it's one of my favorite movies. But much more of a surreal/artistic rendering rather than a scientific one. Another experiment I thought about (I think it's mentioned in the Documentary I suggested) is Dr. Masaru Emoto's water experiments. He took samples of water from the same source and labeled them with different words/phrases (like "love", or "hate", etc) and then observed that the nature of the words being expressed upon the water had a profound impact on the formation of ice crystals within the water. Definitely worth checking out.
