Psychologist Patrick McNamara on the science of dreams. I love that he actually in his study of dreams he's come to realize that something interesting is going on with precognitive dreams that is worth investigating. The commonality of certain recurring characters in one person's nightmares, as well as this nightmare figure sharing characteristics with others is interesting. Here he is on why he doesn't think Mind = Brain. He notes some more interesting stuff about dreams at the end of this one.
