When the time comes for us to move to our higher plane, it will just happen globaly. When it does, you will be confused where you are. Those who are prepared and aware of this occurance, will be able to move on to an existance where time is 3D and not just a linear move. Many others will be there as well. Those who are not prepared and have a closed shakra will more than likley have a sort of Matrix effect. Meaning they won't understand what happened and manafest earth by their memory willing it to become their reality again. They will also be able to bring their bodies back from this current dimention as well to continue their earthly existance without knowledge of what took place.
Now this may sound like a better way to go (ignorance is bliss) but its more like a punichment of reincarnation until they are ready to rise to this higher plane. To achive this higher conciessness is the greatest achivement the human race has made yet. I know this might sound a bit heavy, but that's because it is.
