The numbers mentioned by the entity in the experience remind me of something I've read before, and I dug it up for you. It's in the book "The Holographic Universe" and is related to a researcher mapping the human energy field with the help of electromyograms (which actually means measuring the electrical activity of a muscle). The frequencies in the brain range from 0-100 with an average of 30, but the frequencies this researcher detected in the energy field vary greatly and seem to do so according to their focus of consciousness - materialists would stay within the range of up to 250 (which are frequencies still found in the body), psychics and healers range about 400-800, channelers operate within a band of 800-900 and mystics range at 900 and beyond. (see page 175pp.)

This is one of life's fun synchronicities. Without saying this is the frame of reference your helper chose, it shows it isn't entirely arbitrary either. I wonder how a researcher would assess who is healer, psychic and mystic, however.

The soul-alien-spaceship connection I have from Kurt, but the details elude me right now. A similar reference appears in "The Multi-Dimensional Human":

When we start to use our inner senses, it’s easy to take what we perceive literally. We’re likely to confuse nonphysical realities for physical ones.

For example, UFO sightings may develop from a superimposition of inner sense and physical sense data. The result is belief in a physical space ship and aliens, when the actual vehicles and entities may originate in nonphysical reality.
(Kurt Leland, "The Multidimensional Human")

When you say "does it represent myself in different incarnations?" I have to say I have wondered about this, too. Entirely possible. It could even mean the coming together of self-aspects, and in this the puncture would even become a de-fracturing of the personality. Without further information the "coming together" and the blissful/wellbeing aspect of it certainly indicates improvement, communion and other positive things associated with this ray of light.

The thing about any scale is that there is no scale that isn't arbitrary. Even though some scales in physics reference absolutes as their anchors (like the Kelvin scale and the absolute zero), the actual unit is absolutely arbitrary. Here you were given a comparison - assumption is that the potential of human development is about 800. And that implies there's a zero. So you can say that roughly - if the scale is linear - humanity on the average does not excel even less than 10% of what it could be in terms of human potential.

From your point of view I would take note that the entity has just made a general statement - the average of humanity and a potential, thereby outlining a scale. It hasn't put you into this frame of reference. Unless you think of yourself as the average human, lucidventures and all.
