what is the "density" exactly means?

[Peregrinus]

We were talking about the 4D graduates. Again, initially the dual-activated people will be accessing 3rd-density societal mind - being mostly wanderers, esp initially, they will be confused due to coming from different logos. There will be a lot of odd people around - like L.A.

Where do/did you get the idea that most dual activated mbsc are wanderers?

Once the 3rd density veil thins enough, there can be no confusion among wanderers, for being aware/conscious will remove any possibility of confusion or misunderstanding, even if such may be possible for those of 4th density graduation.

I don't see why the emphasis on 3D being 15 million years gone.

I was simply saying that formation of a social memory complex will not begin for many millions of years in 4D, and as such, discussing how it will interact with 3rd density complex of any type is moot.
