“Seth material” search engine (Jane Roberts)

Man explored the physical world in the dreaming state long before he explored it physically. Such dreams gave him the assurance that other lands existed outside of his own, and spurred him onward into those physical expeditions in which the species has always taken a particular delight.

A man or woman might [be] while dreaming suddenly in strange territory, looking at the sky from a different viewpoint, with, say, a familiar river nowhere in sight, and with a mountain where ordinarily a plain might be. This was in a way as startling an experience as it would be to you to find yourselves on some distant planet. (You do, for that matter, explore space in the same fashion, and on at least some occasions your own “visitors from outer space” are dream travelers from other dimensions of reality. Period.)

As far as group dreaming is concerned, however, there are still some people who have always served as watchdogs in that regard, while others even in the dream state operate as healers or teachers or explorers or whatever. There is no craft that was not first conceived of by an individual dreamer, who later transferred it to the social world of activity.
