The Incubus

Have you ever felt something weird or heavy in front of you while sleeping, as if something is on top of you or trying to choke you slowly... Or have you ever woke up in the middle of the night unable to move your body? It's either you were on sleep paralysis or an Incubus is on top of you. If ever an Incubus is on top of you, you're in for a treat. HAHA!

I don't know if you guys are familiar with an Incubus. I'm talking about the demon not the band.

An incubus is a demon in male form who, according to a number of mythological and legendary traditions, lies upon sleepers, especially women, in order to have sexual intercourse with them. 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. 

There are also creatures called the Succubus, it is the female counterpart of the Incubus.

The exact origin of the myth is unknown, though St. Augustine mentioned sexual creatures in some of his works. The first actual mention of Succubus comes from the 1300's. There are a few basic variations on the myth. In some accounts, the incubus and succubus are two separate demons. The incubus impregnates women with its demon seed while the succubus impregnates itself using a human male. In others, the incubus and succubus are the same shape-shifting demon which needs to collect semen as a succubus first before it transforms into an incubus to impregnate a woman. Less often, these demons use sexual intercourse as a means to directly possess the body of their victims. This is generally done while the victim is sleeping.
