What does it mean to dream about incubus?
An incubus or succubus in a dream often pictures desire tangled with dread, a feeling of being acted upon at night, or a pressure that visits in the dark.
Four ways to read it
Each reading below comes from a named tradition and a cited source, so you can see where it came from and decide what fits your dream.
Freud
Freud would read the night visitor as desire returning in disguise, an urge the waking self forbids and so meets as an intruder. The blend of fear and want is the dream's compromise. Ask what longing arrives feeling as though it is done to you.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might see the incubus or succubus as a dark anima or animus figure, the inner opposite turned predatory when it is denied. It can mark desire split off from waking life. The dream may ask what part of your own longing you treat as a stranger.
Jungian concept (our summary).Modern
Threat-simulation theory suggests the dreaming brain can stage a presence pressing on you in the dark, an experience long tied to the half-waking state and its sense of a weight or visitor. Stress and broken sleep can feed it. Notice whether the figure frightened you, drew you, or both.
Threat-simulation theory (our summary).Mythological
Across folklore the incubus and succubus come at night to lie with sleepers, blamed for restless, oppressive dreams. They were old explanations for desire and dread felt in sleep. The image tends to weigh how you hold longing that feels beyond your choosing.
