Inspired by an ayahuasca trip?
I was told this movie was written after a ayahuasca trip. Ayahuasca contains DMT. If you want to learn more about it I suggest you watch the film DMT The Spirit Molecule.
I'm guessing they saw a vision of the future resembling the one we're presented in this film.
I found this idea fascinating. I need to re-watch this movie while keeping this in mind.
Has anyone else heard this? Did one of the writers actually admit to this?
