Is possible "jump" a density?

[Infinite]

I found another interesting passage:

W: Would these creatures be of another density and still nonetheless be able to have appeared on this planet and made themselves aware to third-density beings, and what would be the significance of that?

I am Latwii, and we believe we have somewhat more information upon which to begin our response to this query. There are many beings of many forms which inhabit those planes of your planetary existence, which are known as the astral planes. These planes are not of another density, but are associated with the third-density experience. This is much likened unto the form your people take upon the passing through of the stage of death. The activation of the fourth ray or the green-ray body, also known as the astral body, does take place upon the process of death and may pass through many planes of existence which are contained within the astral and devachanic levels of your planet.

The inner planes are not from others densities but are part of 3D. So, the Confederation's entities comes to inner planes of Earth. This explain this passage of LOO:

Therefore, this was not pursued further. There was a landing approximately three oh oh oh, three thousand [3,000], of your years ago also in your South America, as you call it. There were a few attempts to aid your peoples approximately two three oh oh [2,300] years ago, this in the area of Egypt.

The remaining part of the cycle, we have never been gone from your fifth dimension and have been working in this last minor cycle to prepare for harvest.
