Just as conscious contents can vanish into the unconscious, other contents can also arise from it. Besides a majority of mere recollections, really new thoughts and creative ideas can appear which have never been conscious before. They grow up from the grow up from the dark depths like a lotus, and they form an important part of the subliminal psyche. This aspect of the unconscious is of particular relevance in dealing with dreams. One must always bear in mind that dream material does not necessarily consist of memories; it may just as well contain new thoughts that are not yet conscious. C.G. Jung, from Symbols and the Interpretation of Dreams
