Well I didn't get the site I was looking for but came across this which sort of contradicts what was assumed...

There has also been rumor circulating in some esoteric circles about the 7.8 Hz. Schumann frequency increasing and that this implies a raising of the awareness or spirituality of human consciousness. In my opinion, both points are nonsense built upon misunderstandings about the fluctuating and multi-frequency nature of the Schumann Resonances and about the nature of frequencies in general. Even if it were (which would require a significant change in the physical size of the Earth or in her surrounding atmosphere), an increase in frequency does not imply an increase in awareness--on the contrary if anything. From a philosophical perspective, if one were to extend their field of perception out to embrace more space, one would be relaxing their brainwave patterns toward a longer wavelength, toward zero, not increasing their brainwave frequencies. When people say, they are increasing in frequency, or increasing their vibrational rate, and they are referring to shifting from a material form to a light form, or to a more transcendent dimensional form, these terms (used to describe frequencies in the electromagnetic spectrum) are really inappropriately applied. They are implying general concepts of thought only and should be understood as such.
