I know this series is known for being abstract and "weird" but that's typically what I veer towards. My
mind enjoys picking at the bones, connecting the dots, creating theories. It's typically what I do when
I watch Twin Peaks in that with every subsequent rewatch, I form a new theory in my head and watch it
through that lens. I enjoy a rewatchable piece of art with no definite answer. It's like being given a
thought experiment and being told to think for themselves. There are too many people who would rather
have the answer presented to them, out of fear of having to do the work themselves or, more egregiously,
they're afraid of being wrong. Well, with art like this, there are typically no wrong answers so why
shouldn't we discuss our interpretations?
First, I'd like to start with the fact that everything Lain is experiencing is a symptom of Psychosis
and I'm not even saying this to be edgy, I'm saying this as someone who has had experiences with
psychotic episodes. She's alone and neglected, no one typically pays any attention to her so, as she
moved through the world as quiet little Lain, there's no one to notice if anything is wrong. That's
when the internet comes in. Now, if you're a fan of Japanese media at the time, there's quite a few
works on how the internet has affected us as a population. It seems as if it's sprouting up new
mental illnesses and disorders that we had previously never seen before and that's an ongoing theme
in Lain as well. The way the internet exacerbates disorders that stay typically dormant inside the
human mind. The internet is a terrible place for someone going through a psychosis episode, typically
the part of the human brain that tries to connect things is overclocked so putting that person into
a world in which everything is connected creates a special kind of hell for them.
Now, I'm not saying the whole thing is an elaborate hallucination, it's not, but this is a factor
in acknowledging what is happening to Lain.
As the show carries on, we have these exposition points narrated to us about various things in
their world. Information that Lain could have easily picked up and carried in her brain to thread
through into another "connected" piece of information. It's easy to see throughout the show that
not everything we see onscreen is actually happening physically in real life. There's a lot of
metaphor/symbolism going on(ala David Lynch) where you can clearly see that this is how Lain sees
things, not how they actually are. The scene where she sees the "Lain is a peeping Tom" rumor
and immediately sees everyone in her school staring at her is a good example of this. That didn't
happen but it's what felt like happened to her.
So, with this knowledge going forward, let's rush to the ending.
In the ending scene after Lain "reset" the world, everyone is alive and normal again except Lain
who no longer exists. Yet, there are small details that seem to be changed. The men in black are
two electricians working on power lines, we don't quite see Lain's family setting, and Chise, now
alive, seems to basically replace Lain. If we take this version as reality, then perhaps Lain as
we saw her didn't really exist at all?
A thought: Lain seems to only exist as an internet persona yet she does genuinely seem to have
lived at some point. Perhaps the left over data of a girl who died? One who experienced psychosis
and killed herself? There's quite a lot of imagery of Lain killing herself in this.
My main theory is that Serial Experiments Lain is both about the events leading up to and after
Lain's death, only, they're sort of merged together into one thing. To bring up the movie Pulse,
the dead reside almost omnipotently using the internet- as they do in a more general sense in
real life. You've seen it before, someone's online presence remains forever long after they've
died. Through the internet- Lain can still continue to live.
"You're software, not hardware" ect.
There's various things I noticed with this theory, most prominently being the large, tumor-like,
overgrowth of computer parts bursting out of her house. The way Arisu doesn't know who Lain is
but also does as if their flow of information passed at one point or another. The fact that
Lain is able to still "exist" in the world in the end as a non-person, watching over everyone
not like a god as some delusions of grandeur would want but as a passing spirit in a crowd.
I think Serial Experiments Lain is about a lot of things. It's about how the internet can
give someone the ability to live in a way they're not allowed to in real life. It's about
how overcrowded it can be, essentially putting hundreds of people into one room and have
them just tell us their thoughts. It can even be a catalyst to events that occur in real
life. The problem is that breaking the wall between what happens online and what happens
in the world can create untold amounts of damage, blur the lines or reality, and allow
us to carry the thoughts and accounts of people we will never know.
