“You are bound to have, then, many larger dream formations that can only be called group dreams – subjective events in which your own dreams happen, and in which your own dreams take part. You expect all of the elements of the physical world, however diverse, to fit together and form a certain kind of permanency and order. It should be no surprise, then, that this kind of “fitting together” includes subjective life also – or that, say, your private dreams are also fragments in a vaster dream reality. They are as important to the operation of that reality as electrons are to your physical one, providing inner pathways for the accumulation of wisdom and pleasure.
“There are certain kinds of dreams in which the various species then communicate, and in which the energies of the environment and its inhabitants merge. These include a kind of horizontal psychological extension, the translation of one kind of dream into another kind – the transference of information from one system to another, in which the symbols themselves come alive.”
