The term ‘Dream Time’ occupies a charged intersection in the depth-psychology corpus, drawing together neurological, mythological, phenomenological, and metaphysical registers. At its most fundamental, the concept names the peculiar temporal structure of dream experience itself — the way dreaming seems to collapse linear succession into simultaneity, rendering past, present, and future coextensive within a single nocturnal event. Von Franz, drawing on Jungian foundations, pursues this most rigorously, arguing that the unconscious operates in something approaching a ‘block universe’ wherein temporal sequence dissolves and events are perceived as a simultaneous cluster. This resonates with the Jungian axiom, noted by Freud as well, that the unconscious ‘knows no time.’ Jung himself, in his seminars, maps dream time onto a cosmic vantage point — the soul seeing the river of life from above. A separate but related strand engages what Jung and von Franz call illud tempus, the primordial mythological time accessed in dreams, coma, and ecstasy — the ‘aljira’ of Aboriginal cosmology, in which time did not yet exist but always coexists alongside historical time. Hillman complicates this by insisting that dream time belongs to the underworld’s qualitative topology, not to chronological measure. The corpus thus presents dream time as simultaneously ontological claim, clinical datum, and mythological category.
