One of my all time favorite tropes is "Everyone is Jesus in Purgatory":
Memories of that overzealous English teacher who forced you to accept that every character, every scene, and every action had a deep inner meaning have led to widespread fear on the part of readers and viewers everywhere that every tale secretly contains some other story being told in subtext.Which seems like a pretty good metaphor for Discordianism to me. Discordianism is post-modern religion. Everything has a deep symbolic meaning if you think about it long enough. Everything is true, false and meaningless (in some sense). Everyone is the Messiah and everyone is Satan AT THE SAME TIME. You are responsible for your own salvation. You are responsible for your road to Hell. You alone get to decide what meaning everything in your life has. It doesn't matter in the long run since the Author is dead and has been for a very long time.
The end result of this is a state of mind that, for example, interprets every plot as an allegory for the afterlife and every protagonist as a stand-in for the Christ: Everyone Is Jesus In Purgatory!
