If you have not watched evangelion, you should, it’s pretty good and pretty short (the entire series is 10h).
Spoiler for the ending of evangelionThe third impact, causes “Human Instrumentality”.
Human instrumentality is when the barrier that separates one soul from another is broken.
When that happens, everyone must face the reality of their true self and of other people.
At least four episodes in the show are mostly in this state, completely detached from the real world, exploring the mind of the characters.
