This category is for fictional succubi — a demon in female form, or supernatural entity in folklore, that appears in dreams and takes the form of a woman in order to seduce men, usually through sexual activity. The male counterpart to the succubus is the incubus. The hybrid-offspring of a succubus is a cambion. Religious traditions hold that repeated sexual activity with a succubus may result in the deterioration of health or mental state, or even death.
