I am not in nexus, I'm not so sure about collective meditations. Stewart Swerdlow mentioned that such things could be used for programming by the PTB. Other paradigms for how this change is going to come about exist.
A quote from On The Way To Supermanhood by Satprem:

It is a direct power of the truth of each instant and each thing harmonized with the total truth of the millions of instants and things, a “power to enter” the truth of each gesture and each circumstance, which accords with all other gestures and circumstances because Truth is one and the Self is unique, and if this point is touched, everything else is instantly touched, like cell and cell of the same body. It is a tremendous power of concretization of Truth, acting directly upon the same Truth contained in each point of space and each second of time, or rather, compelling each moment, each circumstance, each gesture, each cell of matter to yield its truth, its right note, its own innate power buried under all the layers of our vital and mental accretions-a tremendous truing of the world and each being. We could say a tremendous Movement of “realization”-the world is not real! It is a distorted appearance, a mental approximation, which looks more like a nightmare, a black and white translation of something we still have not seized. We do not have our real eyes yet!

For, in the end, there is only one reality, and that is the reality of Truth-a truth that has grown, that had to protect itself behind walls, to limit and dim itself under one shell or another, one bubble or another, to make itself felt by a caterpillar or a man, then bursts open in its own Sunlight when the wings of the great Self we always were begin to open.
