Try thinking of 'things' using the notion that Time is dimensionally a volume not a linear expression. We mortals have aspects of us which are 'limited' to a lesser expression of dimension time, that being a linear reltionship to the greater Universe. In essence, we collect data/information in a linear temporal fashion, our minds (the mind of our soul ... not into spirit yet) assimilate that data in a planar temporal fashion, to construct a meaningful 'present' for contextual purposes to past and extrapolation of future.
A phase shift might entail suddenly collecting information in a planar temporal fashion, thus shifting our 'assimilation' potentials to a completely different frame of reference. ... 'We shall all be changed, in a moment, in the twinkling of an eye.'
