Well, there’s no better example than Inland Empire, a film so unsettling, weird and dark that it will confuse your brain to the point when it just can’t make sense out of anything anymore.
That results with your brain quitting on you and deciding it’s the perfect time to reboot during a nice, 8-hour nap.
And don’t you worry about any nasty dreams – you’ve seen the film by this point (at least one part of it) and there’s no dream weirder than the reality of Inland Empire.
