This documentary Philip K. Dick - A Day In The Afterlife (youtube.com) came up in my feed.

I hadn't completely finished listening. and now I see his main point is about government and fascism and that we should take it seriously so we can avoid it as much as possible, so it wasn't just a talk about a curious timeline phenomenon. I'm not familiar with him but apparently he wrote a lot along these lines and was being spied on by the government, I guess because his themes weren't good for their overreach.

I can't get the parallel time idea out of my head and it's changed how I'm perceiving things. I really dig ideas like this which question basic perception and the structure of things. They can't be refuted if one has some humility, so they can be powerful.
