A succubus is a demon or supernatural entity in folklore, in female form, that appears in dreams to seduce men, usually through sexual activity. According to religious traditions, repeated sexual activity with a succubus can cause poor physical or mental health, even death. In modern representations, a succubus is often depicted as a beautiful seductress or enchantress, rather than as demonic or frightening. The male counterpart to the succubus is the incubus.
