The trance personality occupies a peculiar crossroads in depth-psychological literature, marking the point where altered states cease to be mere episodic phenomena and solidify into structured, semi-autonomous psychological configurations. The corpus treats this term along two distinct but intersecting axes. The first is historical and anthropological: Dodds, working from Greek and late-antique sources, identifies the trance personality as an entity that forms through repeated mediumistic practice — a habituated psychic structure that 'gods' enter with increasing ease once the pattern is established. The second axis is clinical and traumatological: Herman and related trauma theorists locate the trance personality as an extreme product of dissociative adaptation, emerging most forcefully in children endowed with high trance-state capacity who are exposed to severe, prolonged abuse. Here the trance personality shades into what Herman calls 'separated personality fragments with their own names, psychological functions, and sequestered memories.' Jaynes brings a neurological-historical frame, reading trance as a vestige of bicameral cognition, while Jodorowsky rehabilitates trance as heightened rather than degraded consciousness. Taken together, the corpus reveals an irreducible tension: is the trance personality a pathological dissociative defence, an archaic spiritual inheritance, or both simultaneously? The answer varies by tradition but never fully resolves.
when a trance personality has been established.) We do not hear that these 'gods' furnished any proofs
Dodds identifies the trance personality as a learned, habituated psychic structure in mediumistic practice, noting that possessing 'gods' gain entry more readily once this configuration is consolidated.

some children, perhaps those already endowed with strong capacities for trance states, begin to form separated personality fragments with their own names, psychological functions, and sequestered memories.
Herman argues that constitutional trance-state capacity, under conditions of extreme early abuse, becomes the generative mechanism for the formation of dissociated alter personalities.

the hypnotic trance is called just that. It is of course usually different from the kind of trance that goes on in other vestiges of the bicameral mind.
Jaynes distinguishes hypnotic trance from the deeper trance states of oracles and mediums, situating both as remnants of an archaic bicameral mental paradigm in which normal consciousness is diminished or absent.

a trance is not an unconscious or irrational state. It begins with an intensification of attention and ends with the abolition of the spectator/actor reality.
Jodorowsky reframes trance as a state of heightened rather than diminished consciousness, in which the rational island remains intact but becomes connected to broader subconscious landscapes.

The ability to hold contradictory beliefs simultaneously is one characteristic of trance states. The ability to alter perception is another.
Herman links trance states to the paradoxical cognitive structure of 'doublethink,' characterizing them by simultaneous contradictory belief and perceptual alteration under extreme duress.

This altered state of consciousness might be regarded as one of nature's small mercies, a protection against unbearable pain.
Herman frames the dissociative alterations of consciousness that precede full trance personality formation as adaptive, pain-mitigating responses to inescapable traumatic threat.

The occasions of bilocation—sleep, trance, and death—are those when the free soul leaves the body
Bremmer situates trance within the archaic Greek concept of the free soul, wherein the trance state enables the soul — and with it a distinct mode of personality — to separate from the body and engage independent experience.

the psyche operating not to link but to de-link — to split or to dissociate... the defense is life-saving, but then later mistakes every 'flash of light' for the original catastrophe
Kalsched's account of traumatic dissociation provides the structural-psychological substrate from which trance personalities may emerge: a self-protective splitting mechanism that becomes compulsive and self-perpetuating.

Alterations in consciousness generally involve a failure to create such episodic and semantic memories in any part of the personality
Van der Hart distinguishes alterations of consciousness — including trance-like states — from structural dissociation proper, on the basis that trance fails to generate the segregated episodic memories that constitute autonomous dissociative parts.

The complexes can become so dissociated from the ego-personality and even from each other, and they can gather to themselves such strength and form, that they become independent personalities
Hillman, following Jung's complex theory, describes the developmental continuum from dissociated complex to independent personality — a background condition that contextualises the emergence of trance personalities.

'possession' is necessarily a state of hysterical excitement... apart from her mediumship she had no particular gifts
Dodds cautions against conflating possession trance with hysterical excitement, insisting on a phenomenologically precise distinction between mediumistic trance personalities and mere emotional disturbance.

Ferenczi's index locates trance states as a recurrent clinical category in his diary, closely linked to relaxation technique and to the extreme psychic withdrawal he terms 'giving up the ghost.'
