Possession: The Forces That Take Over
We all know it instinctively. When we observe it in someone we love and we can’t reach them or resolve a conflict or repair, no matter how hard we try to connect or care. Going in to try to communicate and connect just backfires. Or we know it most intimately in ourselves. When we look back on our behaviour or perhaps even a decision and can’t make sense of how we chose to act. Even in the blurts that come out of our mouths that we didn’t consciously choose but might cause harm. When people don’t seem like ‘themselves’ or we get into a funk or state we can’t break, no matter how hard we try. No matter how many nervous system hacks we try ;).
We all can become possessed by unconscious material, the shadow that exists in everyone’s psyche. And this shows up on a spectrum. The strength, destruction and intensity can vary. Something else takes the steering wheel, for a moment, a day, a week or a life, eclipsing consciousness in a more enduring and potentially pathological way.
Jung came to the concept of possession through both study and then lived experience during the years following his break with Freud, between 1913 and 1917, in his confrontation with the unconscious. Something in his own psyche struggled to take hold of him, organizing his thoughts, images, and body around a force that didn’t answer to his will. He decided to study himself, document, draw and paint this experience.
In this study of his own unconscious, he entered a field of study that was already in motion.
In late 19th century France, the psyche had already begun to lose its assumed unity. At the Salpêtrière, physicians observed patients, most often women, whose bodies and consciousness didn’t hold a single centre were states shifted, memory fractured, voice and posture changed. The personality of patients reorganized themselves in real time.
Dr. Pierre Janet gave this its first structure. His theory formed through patients like Léonie, whose psyche moved between distinct states, each with its own memory, tone, and continuity. Janet followed the mechanics of this division closely and observed how psyche could split. Parts could operate independently and control could shift.
Around him, others traced the same disturbance through the mind and body.
Augusta Dejerine Klumpke worked where psyche and body meet, tracking how disturbance takes shape in the nervous system. She studied patients whose symptoms moved through the body without clear lesion. Paralysis, sensory loss, and functional disruption appeared without structural cause. She followed how experience imprints itself in the nerves, disturbance organizes into physical pattern, and control within the system can shift outside conscious direction.
Psyche and body move together here and one takes form through the other.
The early evidence for possession came through women whose psyches didn’t remain unified.
Bertha Pappenheim, treated by Breuer, moved between distinct states of consciousness. Her memory broke apart, language shifted and different positions within her psyche spoke and acted without continuity.
Blanche Wittmann, observed under Charcot, entered powerful states under hypnosis where her body reorganized through rigidity, convulsions, and emotional intensity appearing without structural injury.
Hélène Preiswerk, Jung’s cousin, entered trance states in which different voices emerged with their own tone, memory, and continuity. Jung followed these states carefully, observing how they organized themselves over time.
The concept of ‘parts’ and possession came long before Janet as well. Franz Anton Mesmer in the late 18th century described states in which individuals entered altered conditions of consciousness under what he called “animal magnetism.” While his theory of a magnetic fluid was later rejected, the phenomena he observed, trance, convulsions, shifts in identity and perception, pointed toward the psyche’s capacity to reorganize under forces not governed by ordinary will.
In the early 19th century, Marquis de Puységur refined these observations through what he called “magnetic somnambulism,” where individuals entered trance states in which they could speak, perceive, and act from a different centre of awareness. These states often carried coherence, memory, and perspective distinct from waking consciousness.
Later, Jean-Martin Charcot at the Salpêtrière brought these phenomena into medical study, observing how what was referred to as ‘hysteria’ (informed through the oppressive patriarchal lens women were observed through) could produce dramatic shifts in bodily state, identity, and behaviour, often under hypnosis. What had once been attributed to spirits or magnetism began to be studied as a function of the psyche itself.
The field reorganized in response to what these women were living.
They lived within conditions that constrained direct expression; conflict, desire, contradiction, and intensity often had no clear path into speech or relationship. The psyche adapted, reorganized and distributed experience across states, moving through the body and speaking indirectly.
And yet, what moved through them can’t be reduced to social conditions alone because these states carried pattern, repetition, and structure that extended beyond personal history.
Jung enters here and follows the movement further. A split psyche doesn’t remain inertl and our parts act and carry affect, direction, and perspective, interrupting the ego and reorganizing the personality.
Jung names these formations complexes. Each complex gathers memory, image, and emotion into a system that can take precedence within the psyche. We all have complexes. They’re a natural part of psychic anatomy and some are more powerful than others. And some situations or collection of stressors can constellate one or several at the same time, taking the wheel of our mouths, bodies, hearts.
This is where possession begins to take its psychological form as more than fragmentation. It’s something within the psyche takes position and our organizing centre shifts.
The ego no longer governs, decides, reflects, or mediates and becomes colonized by something else that carries its own logic, affect, and authority and it may not be tracked through nervous system dysregulation.
We continue to think, speak, and act from where? That’s the question possession asks.
Jung follows the structure deeper.
At the root of each complex lies an archetypal pattern that doesn’t belong to the individual alone but also to the structure of the psyche itself. They appear across cultures in myth, religion, ritual, and visionary experience and carry inherited forms of human experience.
Between 1913 and 1917, Jung encountered these patterns directly. In his confrontation with the unconscious, figures emerged that spoke with coherence and force and they argued, instructed, resisted control, and returned with continuity.
“I have had the experience of being gripped by something stronger than myself.”
These encounters confirmed that the psyche contains centres of experience that function beyond the ego. Our psyche doesn’t only divide and can organize around patterns that exceed the individual.
This was never a new discovery.
Across cultures, this structure had already been recognized and named.
Experiences of being overtaken by gods, spirits, or forces were understood as real events. They reorganized perception, behaviour, and identity.
Ritual developed around this, not as symbol alone, but as structure and support.
Some traditions moved to expel what had taken hold. Others created space for it to enter and leave in a contained way. Some trained individuals to withstand it without losing position.
The form changes and the underlying recognition doesn’t.
A force can take the psyche. The question becomes how it’s met in a healing context and a cultural context.
Jung’s work stands in continuity with this, even as he relocates the experience within the psyche. He doesn’t remove its force. Archetypal patterns behave in ways that mirror these older descriptions and can displace the ego.
He names the quality of these encounters the numinous, an experience that carries force, fascination, and authority.
Toni Wolff followed these movements with equal precision:
“The individual woman is at times seized by a form that is greater than she is, and she lives it before she understands it.”
Her work tracked how archetypal patterns take shape in lived experience, especially where the tension between personal life and archetypal form becomes acute.
The body remains involved throughout. Jung observed that emotionally charged complexes take hold of physiological processes. The pattern settles into the organism and becomes difficult to shift.
What moves psychologically can take form physically and what moves archetypally is lived through the body, possession both mental and embodied.
It can alter posture, tone, perception, impulse, and relational stance and moves through the nervous system, reorganizing the field from within. It can look absolutely ‘normal’ too, hard to track in ourselves or others but no less potentially destructive.
Earlier religious traditions provided structures that could hold these experiences. Ritual, symbol, and myth gave shape to overwhelming psychic forces and allowed for encounter without collapse.
Jung observed a shift in the modern world where theses experiences remain but the structures have weakened to understand them.
These forces now move more directly into consciousness, shaping identity, belief, and behaviour without mediation. They can appear in individuals and in groups and organize perception often reinforcing repetition, moving through shared emotional fields.
So possession can be both individual and collective where a pattern takes hold, spreads and organizes a group.
What appears in the individual as possession appears in the collective as psychic infection.
And there’s something further Jung refuses to soften in that not all of what emerges moves toward integration.
Jung’s understanding of the Self includes totality. It carries ordering principles and destructive force. It includes patterns that exceed the ego’s capacity to assimilate.
Some of what emerges doesn’t nor can it harmonize.
It can only take hold.
“A man who is possessed by his shadow is always standing in his own light and falling into his own traps...living below his own level.” C.G. Jung
In this state, conviction replaces reflection.
The pattern carries its own authority.
And this is where possession becomes relational.
A complex lives inside a person and also reaches outward.
When someone is identified with a complex, that complex seeks reinforcement. It pulls for agreement and organizes the relational field so it can continue operating.
An analyst can feel this pull. The impulse to soothe, affirm, to align can emerge quickly. Empathy can become participation in a complex. Then the complex stabilizes and recharges even further.
The analytic position requires something else.
To observe without being taken in and to remain in relation without collapsing into the pattern with the other person.
Empathy has a place but it can’t be the only medicine in a therapeutic container. Empathy can backfire where neutrality is required.
Without discernment, it reinforces identification and becomes collusion. Some patterns can be brought into dialogue, require interruption and observation.
And this brings us to what can’t be domesticated.
Jung doesn’t believe these forces can be mastered once and for all. The unconscious, especially at the archetypal level, can’t be made permanently safe, regulated, or resolved.
It’s alive and exceeds the ego.
Even the Self isn’t simply benevolent in a sentimental or soft sense. It orders, but it also dismantles and can reorganize the personality in ways that feel like loss, rupture, or disorientation.
The encounter with the unconscious always carries the possibility of being overwhelmed.
A living, ongoing relationship that requires differentiation, humility, and the capacity to hold position while something stronger moves through.
From a Jungian Somatics perspective, this becomes psychoid, where psyche and body are not separate.
It moves through sensation, breath, posture, impulse, and relational field and reorganizes perception before thought can name it.
But the body registers it first.
The more grounded the psyche is in the body, the more stable the ego’s position becomes in relation to what moves through it.
So the body becomes a site of orientation, not to eliminate these forces, but to remain present in their presence.
This doesn’t prevent possession entirely.
But it changes the conditions under which it occurs.
A psyche anchored in the body can hold tension, can track what is happening as it unfolds. It becomes harder for a single pattern to take the entire field.
Jung places the work here.
Not in eliminating possession, nor in transcending it.
In recognizing when the centre has shifted and in maintaining and objective and discerning position while something larger, at times darker, moves through the psyche.
