Podrag told me to watch this several times and I finally got around to it earlier this year. Something finally clicked on Tuesday and it all made sense: the key is that the memory-swapping is about reincarnation. If you aren’t familiar with the movie you’ll have to read the plot synopsis (spoilers ahead).
Here’s the esoteric cipher:
-The Strangers are the celestial bodies/gods which imprint souls into human bodies. They are using humans as a science experiment to determine the nature of will, fate, and consciousness, in the hope of saving themselves from extinction (the deterministic cosmos being fated to entropy/disorder/chaos/unbeing).
-Murdoch is the awakened superman (woke AF tbh fam) who exerts his will on the world (“attuning” it to himself) and resists fate (the celestial plan).
-The dead woman is Murdoch’s original sin and Shell Beach is his vision of utopia.
-Dr. Schreber is the elite hermeticist illuminarty, retaining his consciousness from night-to-night (i.e. over generations) in order to better serve the gods.
-The perpetual night, itself, is the ignorance/entropy/decay that accumulates in the absence of sunlight, which is illumination/syntropy/order (i.e. Luciferianism).
So…pretty basic bitch anti-Christian stuff, unfortunately (Mr. Book = Jehovah = Bible and rules = “I hate you Dad!” lel). Fun to watch though.
