Spider and Weaving
The spider is typically a symbol of the negative side of the mother archetype and of unconscious fate, ensnaring the dreamer in its web.
The Terrible Mother
As an archetypal image, the spider is associated with the Great Mother, often in her dark and terrifying aspect. The spider possesses many traits attributed to this image: it lures, entangles, paralyzes, and devours. Tolkien explicitly describes the symbol’s negative qualities in the “shelob” of The Lord of the Rings.
Jung states: “The enveloping, embracing, entwining inevitably points to the mother.” (CW Aion, par. 20.)
Fate and Individuation
The spider weaves, much like the Norns, goddesses, and figures such as Penelope. (Note that all these figures are women, aligning with the above.) The web connects the spider with fate, with the “weaving of life.”
Spiderwebs often appear in dreams to illustrate how the dreamer is caught in his or her individual fate. (Visions, pp. 1126f.) It can feel as though the unconscious or the soul has spun a destiny in which one is trapped, like a fly in a spider’s web. Yet this individual fate is linked to the process of individuation, which, in its negative, unconscious, or unaccepted form, manifests as the spider and/or its web.
When one is “caught” in a dream—by a web or a pit, for example—one often finds oneself in the place where one truly belong: one's individual place. “This is one of life’s greatest disappointments,” Jung comments. (Ibid.)
“One senses a kind of unconscious force in the background, for which the spider is a fitting illustration… Thus, individuation as something negative is expressed through the spider’s web.”
This negative image can, over time and with awareness and acceptance, transform into a positive, protective mandala. The spider itself possesses a mandala shape with its body and legs, especially when sitting at the center of a symmetrical web.
Maya – The Web of Illusions
In Hinduism, the spider symbolizes Maya, the illusory web of the external world in which humanity becomes ensnared. As a dream symbol, the spider can express a similar meaning: the dreamer is caught in his or her false notions, such as illusions about the self in relation to inescapable circumstances.
Being Stuck
The web and fate are also tied to the image of “being stuck” in something, or even paralyzed, perhaps by a maternal force. The spider’s web ensnares, and its venom paralyzes.
Spinning
However, the web can also entangle the dreamer, binding him or her into another world; for example, thoughts and fantasies can “spin” (go round and round) to the extent that the dreamer becomes paralyzed and loses touch with reality.
Spinning is a feminine activity (see Weaving); in a man, it may express his “inner woman,” spinning fantasies that he projects. Unconscious fantasies shape our destiny—bringing us back to the spider’s web.
Trickster
In folktales, rhymes, riddles, and other folk expressions, the spider has a trickster quality—it is clever and playful in folklore. It is a widespread superstition that spiders are connected to luck (a trickster quality) and must not be killed; in some places, killing a spider foretells rain. The spider has even been considered “a friend of humanity.”
Air Demon
According to James Hillman ("Going Bugs"), the spider as a symbol belongs to the air rather than the ground. Though most spiders live on the ground, in dreams and fantasies, they are more aptly described as “air demons.”
The Self
Traits such as the spider’s eight legs, its mandala-shaped web, and its association with fate sometimes make it an expression of the Self—most prominently in its negative aspect, however. It often appears in dreams when we fear the unconscious striving for integration.
