Complexity, Self-Organization, Emergence

Self-organization is more likely to be achieved in undirected states, such as meditation, fantasy, or reverie, that border on waking. Dreaming serves to loosen associations lest they become obsessively tight. Francis Crick theorized that we dream in order to forget. Dreaming may be our most creative conscious state, one in which the chaotic, spontaneous recombination of cognitive elements produces novel configurations of information, that is, new ideas.
