We lately had an article about the succubus, but women aren’t safe while they sleep either. There is a male version, known as the Incubus. An incubus is a demon that visits women at night, lies upon women and engages in sexual activity with them. They are believed to have a unnaturally large, ice cold penis, and some say even men aren’t safe: the Incubus is said to be bisexual.
There’s also a Californian rock band called Incubus, but their nightly activities are slightly different from visiting unsuspecting sleeping women at night.
