A figure appearing in dreams as a double or hidden self, embodying traits, drives, or identities suppressed or unrecognised in waking life.
The alter ego appears in dreams as a person who is simultaneously familiar and strange — often a shadowy twin, an uncanny double, or a figure who acts in ways the dreamer would not. It may bear the dreamer's own face, share biographical details, or simply carry an unmistakable sense of *being* the dreamer under different circumstances. The encounter can be antagonistic, collaborative, or profoundly unsettling in its intimacy.
The range of meanings is wide. The alter ego may represent disowned ambition, repressed sexuality, an unlived vocation, or the moral inverse of the dreamer's self-presentation. In some dream sequences the figure pursues the dreamer; in others it offers guidance or performs actions the dreamer wishes to take but cannot. Repetitive encounters across a series of dreams often signal an ongoing psychological negotiation rather than a single resolved meaning.
The motif of the double has roots in ancient folklore (the *doppelgänger*, the *ka* of Egyptian belief, the *fetch* of British and Irish tradition) and persists across Romantic literature — most notably in Poe, Dostoevsky, and Stevenson — where the double externalises an interior moral or psychological conflict. Dream research has inherited this cultural preoccupation, making the alter ego one of the more theoretically loaded figures in the symbolic vocabulary of dreaming.
Jungian
Jung's concept of the Shadow is the primary lens for the alter ego in analytical psychology. The Shadow is the unconscious counterpart of the persona — containing qualities the ego has refused to integrate. When the alter ego appears as a threatening or morally compromised double, it typically represents Shadow material seeking recognition. Jung distinguished this from the broader concept of individuation, in which integrating — not defeating — the double is the goal. Edward Edinger extended this, noting that the confrontation with the double is a critical stage in the individuation process, often preceding a significant expansion of conscious identity.

Freudian
Freud addressed the uncanny double directly in his 1919 essay 'Das Unheimliche', drawing on Otto Rank's prior monograph on the double (*Der Doppelgänger*, 1914). Freud situated the double's uncanniness in its origin as a narcissistic projection — an early ego-ideal that, once the reality principle establishes firmer self-boundaries, becomes alien and threatening. In dream terms, an alter ego figure may represent the return of repressed wishful content: the double enacts what the dreamer's superego prohibits, making it simultaneously desirable and persecutory.

Cultural
Belief in a spiritual double that shadows the living self appears independently across many cultures. The ancient Egyptian *ka* was a vital double born alongside the person and surviving death. Germanic and Scandinavian folklore described the *doppelgänger* as an ominous harbinger seen by others before the person's death. Irish and British traditions spoke of the *fetch*, a wraith of the living sometimes appearing in dreams. Mircea Eliade's comparative work on shamanism documents the soul-double as a technical concept in numerous indigenous traditions, where the dreaming self routinely separates from and encounters its counterpart.

Neuroscientific
From a neuroscientific perspective, the alter ego figure can be understood in terms of self-referential processing during REM sleep. The default mode network — active during self-related thought — remains engaged during dreaming, but with reduced frontal oversight. This permits the generation of character agents that share autobiographical features with the dreamer while behaving independently, producing the phenomenological sense of a 'self-other'. Research into agency attribution during dreaming (Hobson and colleagues) suggests that characters who feel like versions of the self may reflect fragmented self-models assembled from episodic memory without normal executive coherence.
