Besides the dream and the deep sleep there are visions. These are seen when the soul in sleep is active in the higher spheres. What it sees there the mind interprets in allegorical pictures. The soul sees plainly the actual thing, and whatever the mind receives from its impressions is more or less what the soul sees. Therefore the thing is seen as a picture, an allegory, a parable, which the sage can interpret, because he knows the language of those spheres. If he sees himself going down or walking up a mountain, if he sees himself in rags or very richly dressed, on an aircraft or in the desert, he knows what it all means. The ignorant one does not know; he merely thinks it is a dream and nothing important.
