Supremely underrated Carpenter film. Super thought provoking for me, not in the way the storyline of the movie unfolds but rather potentially what we experienced as interaction with Divinity and Evil, spirituality could actually be spirits interacting with us in the material plane at the quantum level. I once in the early 90's (1992, I think) tried to explain it to one of my college football coaches after practice and he thought about it for a few minutes and ask me very seriously if I was experimenting with drugs. I had to tell him I was talking about advanced physics, not psychedelics. I was only at that school for a semester.
I literally just woke up and I was in prehistoric Britain traveling with a band of Arthurian knights and once we started getting overwhelmed, we time traveled to a Depeche Mode concert and then I woke up.
