Didn't mean to hijack your thread and go off on a time tangent. It's just such a fascinating topic to me that I get carried away with it. Only one more mention of time though as here is a good compilation of all thoughts regarding time made by Wikipedia:

   I like your concept of frequency shift rather than time shift to change focus levels. All time means to me is a word representing a continuous succession of nows. Frequency, however, maintains integrity as a measured oscillation allowing something resembling space to come into play.

   Without space, where would we be? Focus levels could possibly be in the same space as the physical universe, but coexisting out of phase with us in our incarnate existence by maintaining a different frequency or vibrational rate.

   I've pondered this issue most of my life and am always open to any new sources of information. When I finally become adept at leaving my body and/or phasing my consciousness into different focus levels while retaining memory, then I can devise a decent theory of my own. Hopefully with all of our collaboration, we can formulate a reasonable understanding. Sort of how partnered exploration of the afterlife has helped in understanding what is most likely true.
