The succubus is a female demon from European demonology, known for seducing men in their sleep to drain their vital energy, often through erotic dreams. Depicted as an extremely attractive woman, sometimes with demonic features like wings or claws, she symbolizes the danger of desire and lust. Emerging in the Middle Ages, her myth has been linked to sleep paralysis and sexual repression. Over time, the succubus has become a cultural archetype of the femme fatale, appearing in literature, art, and modern media as a symbol of seduction and mystery.
