If you are curious about some really interesting material on this topic, you should read some Catholic prophecy. They all say essentially the same thing.
A good one that compiles almost two centuries worth of Catholic Prophecy is this book:
Catholic Prophecy: The Coming Chastisement by Yves DuPont
God has always historically given the world a warning before He chastises it, and so that 'shift in consciousness' will be the Warning before the Great Chastisement. The Warning will be an event where everyone in the world is given the view of their soul as God Himself sees it. This will be so incredibly frightening that a few people may die from it, but it will bring about the conversion of many sinners, while increasing the fervor and devotion of the just. Of course, there will also be those who are obstinate in the face of the Warning and still refuse to recognize God.
Then the Great Chastisement will come (also known as the Three Days of Darkness) and there will be a short period of peace following. After that will be the Final Battle and then Christ's Second Coming in triumph to end this world.
Google the Apparition of Our Lady of Garabandal Spain, which has more info on these prophecies.
Actually this is the kind of stuff that my mom was into and traumatized me. Something doesn't sit right with me about the Garabandal appartions. PM me, Stacy, if you'd like to discuss!
