OP - It has happened without any "action" on my part, and it has happened with "action" on my part where I have submerged myself entirely with an alternate reality of sorts.
It's like looking through the world with a new pair of eyes.
There are also ways to suspend disbelief, or to dip into denial to cushion your everyday with pleasantries, rather than self vindictive, and potentially unrealistic "realities".
I've skimmed through the thread. I didn't realize this was an "Asburgers" or an "Autistic" thread. I might be either or, I've certainly had others call me it in the past.
I'd say when it's the day to day it's creative at work.
When it's "out of this world" temporarily, it's potentially spiritual.
