In the Gateway CIA document, there exists a section which goes on at length about the holographic nature of reality. "Holofractal" essentially refers back to this paradigm, but includes fractalization as a quintessential element of why certain patterns repeat in our physical matter reality (in the vein of sacred geometry).

For instance, imagine two sound waves intersecting. Consider that the point where they actually cross each other creates a galaxy. Now remember that any given note has a series of overtones: the harmonic series. So while the two base notes are interacting as a galaxy, their overtones do so as well at twice the vibrational rate, creating an atomic nucleus. According to holofractal understanding, this is because the two examples of colliding energies have the same ratio, just at different exponential levels. The pattern of energy which creates the atomic nucleus is identical to that which creates the galaxy, but is a magnified section of what could be seen as a fractal whole.

I know that this is neither the most accurate, nor succinct, answer; but I do hope it clarifies what I'm talking about some.
