Don't limit yourself. Envision what it would be like for people to work together toward the goal of reaching right into the "supernatural."
Well, that's difficult for me because in my own belief system I consider "supernatural" to be a synonym of "imaginary".
As far as what people can work together to achieve, I have no idea and I'd be pretentious to pretend I did. I suppose that acutely it has a lot to do with whether or not our species kills ourselves off with nuclear weapons or too much carbon dioxide in the upper atmosphere.
