Past-life regressionist and hypnotherapist Dolores Cannon specializes in the recovery and cataloging of “Lost Knowledge” and metaphysical information which she acquires by taking clients into a deep trance state, without interference from the conscious mind. We exist within multiple dimensions, and move between them without our conscious awareness. Dimensions vibrate at different frequencies, and this is one of the ways that ETs travel– they raise the frequency of their craft to exit (which to us looks like they are disappearing), or lower their vibration (become denser) to enter.
Cannon believes that ETs seeded Earth and created humans, who were given free will to see how they would develop. A kind of ‘prime directive’ is in effect, so the aliens cannot directly intervene, and that is why they have been known as ‘the Watchers’ for eons.
