An Incubus is a demon in male form supposed to lie upon sleeping women in order to have sexual intercourse with them, according to a number of mythological and legendary traditions. Its female counterpart is the Succubus. An incubus may pursue sexual relations with a woman in order to father a child, as in the legend of Merlin.
Religious tradition holds that repeated intercourse with an incubus or succubus may result in the deterioration of health or even death. In medieval times, the church would use incubi and succubi to explain sexual functions, which were taboo subjects.
"Origin: Germany. A male dream demon. It enters women's dreams to have sex with them there. They are said to take men's semen from Succubi to impregnate women."
