|Serial experim. Lain explained with fear factory|
I have been reading thousand of people who didn't get the message of the anime, But I did, It's a darker represention of the matrix saga but even more philosophical than the movies. I could make a connection between fear factory's albums/songs and the history so here we go
Soul of a New Machine
Indeed, in the series the human Lain doesn't seem to have a soul, but she has one when she unifies with the wired, that's why the real Lain is so empty in both personality and characterization.
Lain sees the future of humanity in the network: If you look how society is represented in the real world, there seems to be nothing special or interesting, However, most of the deep thoughts of the humans are shown in the digital world (such us Lain discovering the affair of her best friend with her teacher).
Lain's sister represents the viewer of the anime: Yep, if you take a look in the evolution of the character from the first episode to the last, you will see that in each episode the sister starts to become paranoid, so is probably the people who followed the series. By the end of the series it seems that the mix up of the real world with the virtual one will surely make you think what it's real and what it's not.
Lain does not become a God of the wired, but the chosen one to protect the limits of the virtual world with the real one. Lain is nothing more than the bridge between 2 worlds.
Lain's complex personality is shown thanks to the evolution of her room: Have you noticed that in the first episode Lain's room is just a bed and a nightable? that showed how simple and practical she is, however by the end of the series the room becomes a visual representation of Lain's brain, and thus her dissociative identity disorder.
Lain is the personification of the collective unconscious. She might be a human being in the series, but in reality Lain is actually a social constructionism to justify everything that a rational human being is not able to answer,. just Like Plato's theory of forms represented in modern times..
