A Ghost Story...
We humans get stuck on stupid because we're some of the youngest things to populate this planet. We’ve yet to fully mature/grow up. We humans restrict ourselves to timekeeping using clocks and watches where, in reality, we are capable of oneness with the entire cosmos at once (we each have a personal mind that if allowed can meld with other minds as well as the Mind; something a narcissist cannot do). But, if you keep time, then you disallow your self from the oneness. And, precludes one's self from experiencing the cosmic oneness... each ghost viewed in the movie had Incomplete oneness until they decided/ chose to release themselves from their human restrictions.
