My information says the "real" ascension is to 5th density, and that there are many people who have "bought into" a faux 4D "ascension". That was created in 4D as a "holodeck" simulation of the actual 5D+ ascended reality, to keep souls captured in the Matrix, but believing that they had "ascended". Most of the hoopla about 2012-12-21, and a lot of the "channellings from Arch(on)-Angels were of this deception.
Update
2016-09-03:
Later higher awareness has revealed that even 5D is still within
En.Ki's Prison, therefore we must go even higher to be free.
