“Seth material” search engine (Jane Roberts)

...It means that the personality exists in many dimensions at once. Now this includes not only reincarnational material in your terms, but the realization that the personality in the dream state is actually as alert and conscious as it is in the waking state. Now pretend for a moment that you are your dreaming self. And you want to understand the nature of physical reality. So you must peek out at physical reality, while the body sleeps and the eyes are closed and the senses are “dimmed” in your terms. You would gain little information, and yet you are in the same position attempting to understand the nature of the dreaming state with your waking consciousness.

Once psychology realizes that the personality is also alert and conscious in the dream state, then indeed its precepts and its bases must change. For information is given to you not only in your waking, conscious, alert daily life but in what you would call your unconscious sleep state. Now your sleeping self is awake all of the time—you dream all of the time. Your dream life is continuous, only your waking ego closes out the inner stimuli and does not see it, for it must concentrate upon physical daily reality. But it can learn to look inward, change the focus of its awareness and take quick pictures of this inner environment. So more than reincarnational existences are involved.
