Dreams prepare, announce, or warn about certain situations, often long before they actually happen. This is not necessarily a miracle or a precognition. Most crises or dangerous situations have a long incubation, only the conscious mind is not aware of it. Dreams can betray the secret. They often do, but just as often, it seems, they do not. Therefore our assumption of a benevolent hand restraining us in time is doubtful. Or, to put it more positively, it seems that a benevolent agency is at work sometimes but at other times not. The mysterious finger may even point the way to perdition. One cannot afford to be naïve in dealing with dreams. They originate in a spirit that is not quite human, but is rather the breath of nature-of the beautiful and generous as well as the cruel goddess.
— C.G. Jung
Jung is correcting a fantasy here — not gently, but with deliberate precision. The reader who comes to dreams hoping for a guardian intelligence, a compensatory wisdom reliably oriented toward wellbeing, will find that hope neither confirmed nor simply denied but complicated past recovery. The crisis was already forming long before the dream appeared; the dream may have been reading it, or may not. The benevolent hand is sometimes present, sometimes absent, and sometimes the finger points toward ruin.
This is worth sitting with because the wish for a benevolent agency is itself one of the soul's oldest strategies. If the unconscious is fundamentally on my side, if the dream is a message from a deeper wisdom that wants my healing, then the terror of the psyche's autonomy is softened into something manageable, even reassuring. Jung refuses the softening. The spirit from which dreams originate is not a therapist. It is, in his phrasing, the breath of nature — and nature is not divided between cruel and generous as a defect to be corrected; it is both simultaneously, without apology, and without the slightest interest in which face it is currently showing you.
Working with dreams on that basis requires a different courage than the one dream-as-guidance literature tends to cultivate.
