“Time overlays are versions of master events, in that they occur in such a fashion that one “face” of an overall event may appear in one time, one in another, and so forth.
“Time overlays are the time versions of certain events, then. These time overlays always exist. They may become activated, however, by certain associations made in your present, and therefore draw into your present time some glimpses either from the future or the past. So-called present time is thickened, then, by a psychological realization on deep levels of the psyche that all events are interrelated, and that the reincarnational experiences of any given individual provide a rich source of experience from which each person at least unconsciously draws.”
