Yep, lots of question marks. Lots of probable scenarios. wandering1 has posted an excerpt from The Moment Of Quantum Awakening by Ken Carey, here's my own choice of excerpts, a probable scenario that I like. Note that it says there's no way to predict the effects or results:
At the moment of quantum awakening, change will occur rapidly, rippling across the terrestrial surface like a wave. Everything in the earth's gravitational field will be affected in some way. There will be a time of massive change, of change on a scale that has no historical precedent, though it does have antecedents in the prehistoric events of this and of distant worlds. The changes that your generation will experience before it passes the torch to another are more fundamental than those that accompanied the agriculture revolution-and those changes took thousands of years. They are more far-reaching than the changes of industrialization, which took nearly three centuries to transpire. Yet, deep and fundamental, massive though these present changes are, they will occur within the span of just a single life.
[...]
There will be a great shift then, a single moment of quantum awakening. In this moment, the smallest interval of time measured in these dimensions-this interval that occurs in every atom between each of its billions of oscillations per second-will be lengthened unto infinity. An interval of nontime will expand. Through that expansion eternity will flow. Some will experience this moments as minutes or hours, others as a lifetime. Still others will experience this flash of nontime as a succession of many lives, and some few will, in this moment, know the Nagual itself, the great nameless Presence that exists before and after all these worlds.
In the expanse of the nontime interval, human beings will have all the time they require to realize, experience, and remember full consciousness of their eternal spirits and to recall the origin of their individuality in the primordial fields of being. All will have ample time to recharge their form identity and its biological projection with the awareness of who they are, why they have individualized, and why they have chosen to associate with the planet's human expression. Each one will have the choice to return to biological form or to remain in the fields of disincarnate awareness.
Those who choose to return to human form will do so fully aware of who they are. No longer will they be put partially incarnate; they will resume biological residence with the full memory and consciousness of their eternal natures, sharing the creative capacities of the Star Maker, whose reflective cells they will then know themselves to be.
Subconscious orientation in fear will be replaced by conscious orientation in love. The sudden release of power, as the polarity of the collective human emotional field shifts from outer to inner orientation, cannot be avoided no no matter how smoothly we seek to guide the transition. All will feel an unmistakable surge of power in the instant of quantum awakening. This is as inevitable as the daily rotation of the earth's continents into and out of the light of the sun.
But the effects? The implications? There is no way to predict them. They depend on the choices you make today. By extrapolating current trends of consciousness we can establish a probable range of effect. But there may be as many as eight billion people incarnate at that moment, each with complete freedom of choice. And though the choices each one makes in his or her lifetime prior to that moment will certainly predispose that person in one direction or another, there are no guarantees, no assurances.
