What does spiders mean in a dream?

The spider in a dream refuses a single meaning. Every major tradition in depth psychology has reached for it and come away with something different — which is itself a clue. The image is overdetermined, carrying several symbolic registers simultaneously, and the first task is to resist the diagnostic reflex and watch the image move.

The Great Mother and the web of fate

The oldest and most persistent layer is the spider as weaver of fate. Neumann traces this back to the Moirai — Clotho, Lachesis, Atropos — daughters of Night, sisters of the Erinyes, whose kinship with the Erinyes appears even in cult: at Sicyon they shared an altar and received the same chthonic sacrifices (Neumann 1955). The spider's web is the web of destiny, and the spider at its center is the Terrible Mother in her most archaic form: the one who spreads nets, who devours the male after coitus, who binds and fetters. Onians (1951) demonstrates that this is not decorative metaphor — the thread of fate in archaic Greek imagination had literal ontological weight, the warp-thread of a life suspended from the loom of Ananke.

The spider can be classified among this group of symbols, not only because it devours the male after coitus, but because it symbolizes the female in general, who spreads nets for the unwary male.

This is the uroboric register: the spider as devouring womb, the labyrinth whose center is danger, the net whose center is death. When this layer is active in a dream, the question is not "what does the spider mean?" but "what is the dreamer caught in?"

The chthonic mind

Hillman offers a different reading, and it is the one most worth sitting with. He insists that dream spiders, despite living in the earth in nature, almost always appear in the air in dreams — a nightworld air, chthonic and pneumatic at once. This is the spider as underworld intellect:

There is an underworld intellect, a chthonic mind of nature that must spin out its patterns, constructing networks that can catch and hold any winged fantasy flying by.

The fly caught in the web is the puer spirit — the ever-escaping, lightweight, airy thought — and the spider is the deep mind that can hold it. Hillman's instruction is pointed: "when the spider comes to your dream, do not diagnose it. Turn to the other half of the tandem, yourself, the dream ego. Are you Miss Muffet content on your tuffet, or a little buzz of thoughts afraid of the synthetic imagining power of the deep mind weaving your fate into the organizing intelligence below nature?" The spider's arrival is less a symbol to decode than a question about the dreamer's relationship to depth itself.

The Self and inflation

Jung reads the spider in a different key — as a symbol of the supraordinate totality of the psyche, the Self, but one that carries a specific danger. In one patient's dream, a blue diamond-bodied spider sat at the center of a cobweb in an attic window. Jung's commentary is careful: the image is genuinely numinous, "a rare jewel," but anyone who gets into the spider's net "is wrapped round like a cocoon and robbed of his own life" (Jung 1964). The spider-as-Self is not an invitation to identification but a warning against it. The web is mandala-like, organizing, centered — and precisely for that reason, it can become the trap of inflation, the ego mistaking itself for the whole.

Von Franz adds a temporal dimension: the spider is a negative mother symbol, the Maya, the spinner of fantasies. "When it comes in the evening, or at the evening of life, it is all right, but it is very bad to start the day with it" (von Franz 1980). Fantasy-spinning at the wrong moment — slack, neurotic rumination — is the spider in the morning. Reflective, philosophizing reverie at day's end is the spider in the evening. The same image, opposite valences, depending entirely on when and how the soul meets it.

Intentionality: what does the spider want?

Hillman's later work on animal dreams in Animal Presences (2008) adds a further question: not what the spider means, but what it intends. Dream animals move toward or away from the dreamer with purpose. A swarm of black spiders that scatters when the dreamer walks but mounts force and advances when she stands still is doing something specific — it attends the dreamer, closes in, wants something. The image of a spider crawling over a man in a cave-like room, black widows that stick to him, met without fear: this is integration of the shadow, the dreamer letting himself be "infested by the creatureliness of earth" (Hillman 2008). The spider's intentionality — whether it approaches, retreats, hangs, weaves, or attacks — is the primary datum.

What to do with the image

Hall (1983) observes that frightening dream images frequently transform when the dream-ego turns to face them: a spider covering a window screen, striking terror, walks down into the front yard and becomes a friendly puppy. The transformation pictures the unconscious content's "desire" to become conscious. But Hillman would resist this too quickly — the spider may not want to become a puppy. It may want to be met as spider, on its own terms, in the dark.

The question the image asks is: which web are you in, and are you the weaver or the caught?
