Thought experiments lain: a serial experiments lain information site. Serial experiments lain is an anime which begs to be interpreted (read my review for a basic description of the show).
While the story gives us a lot of hints as to what might be going on, nothing is ever explicitly explained. Even when things are explained in the form of commentary and "speeches" throughout the show, we are shown that the views put forth in those speeches (such as given by Eiri Masami) are not necessarily correct and truthful.
