Something that I find really funny about the somniums in the AI games is that... they're dreams. They're symbolic, exagerated, or otherwise innacurate representations of real-life events. Which means that a solid 80% of the time what you see in somnium is either useless or wildly mistinterpreted by the cast. "Iris" is dreaming of a fucked up murder warehouse filled with bodies? Whack. No idea what that means, though. Sou dreams of Iris being repeatedly stabbed? Surely he did it. Iris has space aliens in her dreams? Proof that she's hunted down by the illuminati!
The only thing you can be certain of when leaving a somnium is that damn, these bitches sure have issues.
