The pillow appears in the depth-psychology corpus along two distinct but surprisingly convergent axes. In the mythopoeic tradition, most forcefully articulated by Robert Bly, the pillow is the locus of the hidden key — the object beneath the mother's pillow in the Iron John narrative that must be stolen if masculine initiation is to occur. Bly reads this image directly through a Freudian lens: the key is precisely where Freud said it would be, indexing the eroticized maternal bond that must be broken for psychic emancipation. This is one of the corpus's most cited symbolic readings of a domestic object. In the clinical-somatic tradition, by contrast — represented principally by Pat Ogden's sensorimotor psychotherapy — the pillow is not a symbol but a therapeutic prop: a physical object used to help trauma survivors regulate autonomic arousal, execute truncated defensive actions (pushing, kicking), and restore bodily boundaries. The pillow here mediates between therapist and client, standing in for the aggressor or providing protective coverage over exposed anatomy. Janet's invocation of Macbeth's deaf pillows, receiving the secrets of infected minds, offers a third, literary-phenomenological register. Hillman supplies yet another angle, using the pillow as evidence against the fiction of a purely private environment. Across these registers, the pillow anchors questions of safety, concealment, embodied defense, and the maternal threshold.
The Wild Man replies, 'The key is under your mother's pillow.' The key is not inside the ball, nor in the golden chest, nor in the safe... the key is under our mother's pillow—just where Freud said it would be.
Bly identifies the pillow as the mythic site of maternal concealment of the initiatory key, reading the fairy-tale image explicitly through Freud as the symbolic threshold of the mother complex that the son must transgress.

The risk involved in getting the key from under the pillow is not worth the effort. 'Please don't make me do that. I'm willing to lead a shrunken life—just don't force me to put my hand under my mother's pillow and take out the key to freedom.'
Bly elaborates the pillow as emblem of regressive resistance, arguing that the son's reluctance to reach beneath it enacts the choice of psychic diminishment over the discomfort of maternal separation.

When Louise experimented with holding a large square pillow that covered her entire torso and genitals, she felt more relaxed. Her therapist encouraged her to use the pillow when she experienced autonomic arousal or defensive strategies.
Ogden presents the pillow as a somatic resource that modulates autonomic arousal by providing physical coverage and protective boundary, enabling self-regulation and social engagement in a trauma survivor.

Try mindfully and slowly pushing against the wall, a pillow, or a big therapy ball held by your therapist. Stay focused on your body and describe how this defensive action feels physically.
Ogden's clinical protocol systematically deploys the pillow as a resistance object for executing truncated fight-defense impulses, mobilizing the body's instinctive responses that were blocked at the time of trauma.

The therapist encouraged the slow enactment of this mobilizing defense, which had not been possible at the time of the trauma, holding a pillow for Martin to push against.
In sensorimotor psychotherapy, the therapist-held pillow enables the completion of previously frozen mobilizing defenses, allowing the traumatic body memory to be transformed through embodied action.

Sally felt powerful and forceful as her muscles engaged in pushing against the pillow held up by her therapist. After the session, she reported feeling fully present in her body and finally having a way to come out of the 'fog.'
Pushing against a therapist-held pillow functions as a somatic resource that restores presence, combats depersonalization, and installs a felt sense of agency in a dissociated trauma survivor.

Jay mindfully used his arms to push out against a cushion held by his therapist, following the impulse of the tension in his arms to fight back.
The cushion or pillow mediates the re-enactment of fight-response impulses, allowing the client to access and complete the defensive action that was prevented during an actual assault.

Janet cites Shakespeare's image of the pillow as the mute recipient of hysterical secrets, positioning it as a literary precursor to clinical understandings of somnambulistic confession and unconscious discharge.

Von Franz cites a fairy-tale motif in which the pillow is the site where magical abundance manifests nightly, linking it to unconscious processes of compensation and hidden generativity.

Even the pillow on which I lie breathing as I float into my private midnight dream bears traces of duck down, polyester, and cotton and the environments from which this pillow was manufactured, as well as of the traffic of mites sharing the pillow with me.
Hillman uses the pillow as a philosophical example to dissolve the myth of a purely private inner environment, arguing that even the most intimate nocturnal object is constituted by intersecting ecologies and histories.

Some of these texts were also called 'pillow books,' a designation that expressed the value of a text in later Daoism.
Kohn notes the Daoist designation of esoteric texts as 'pillow books,' associating the pillow with the transmission of secret, high-value knowledge kept close to the sleeping body.

She suddenly understood her rule not to let the bolster touch the back of the bed. The bolster had always seemed a woman to her, she said, and the upright back of the bedstead a man.
Freud presents a case in which a pillow-like object (bolster) is invested with unconscious sexual symbolism, illustrating how bedding becomes a field for the displacement of conflict around virginity and intercourse.
