All events are multidimensional and each event lives on indefinitely, constantly seeking Value Fulfillment (i.e. Being) and spawning new events in a cascade of creativity. What we recall as dreams are symbolic representations in the language of form that we learned in this physical body. The various depths of our being would experience their own unique experience of dream (and awake) events in the "language" that they speak. Recall that even atoms dream in their own terms.
“In dreams you deal with symbols, of course. Yet symbols are simply examples of other kinds of quite “objective” events. They are events that are what they seem to be, and they are equally events that do not “immediately” show themselves. One so-called event, therefore, may be a container of many others, while you only perceive its exterior face – and you call that face a symbol.
“The other events within the symbol are as legitimate as the one event you perceive.”
(The Nature of the Psyche, Session 792)
