All who receive the proper training can see and communicate with life that exists in other planes or dimensions. To frame that statement in a manner that the acolytes of quantum physics may understand is important. If the physical groupings we call matter are just energy vibrating at various frequencies then by altering our sense perceptions to become in tune with various frequencies we should be able to communicate or at least observe those things which occur on those frequencies. Our current mental outlook imposes limitations that preclude the average person from the ability to visually or aurally become aware of the existence of other frequencies or dimensions. Everyone comes close to realizing this talent when dreaming.
Most adults teach their children to ignore anything they see or are told in dreams.
Our dreams then scare us due to our lack of knowledge. In a culture that encourages the analysis of dreams as therapeutic, like the aborigines of Australia, the whole family discusses each other's dreams every morning. Your immediate family often knows you better than you know yourself. European psychologist Sigmund Freud popularized the theory that your dreams are the doorway to deeper levels of your mind. Talking dreams over with your family is more likely to elicit a correct response than discussing them with a stranger.
