We're currenly transitioning into 4D right now as thoughts are becoming manifestations with relative ease.
If you get the opportunity, please watch Dolores Cannon's "Moving Into a New Earth"

I'd recommend one book in particular, The Convoluted Universe Book Two: Check out Chapter 30: The New Earth. It'll blow your mind!!!
