**WARNING** Demons are not a joke. They are extremely dangerous! Reading a couple books and knowing a few names DOES NOT make you a demonologist. This title has been used by groups. There are only a hand full of "REAL" demonologist. We have one of those elite researchers, that is well respected in the field as a part of our consultant team. Do not attempt a case with a demonic. This is spiritual warfare which affects our very soul.
A sexual Demon? Is there such a thing? They are out there and have been documented as far back as medievel times. It is a demon that takes the form of a Female (Succubus) or Male (Incubus) and has sexual intercourse with it's victim while they sleep. This can be violent in nature and women are able to be inpregnated. It gains energy for it's own survival and will drain it's host of their life force. A demon will often mask it's true identity to gain your trust, this type of demon is no different from any other.
Both of these demons can become the opposite also. It seems their attacks are during the victims sleep. This is when a lot of ghostly or paranormal activity is reported, just before someone falls asleep, during rest or as they are waking up. This is possibly caused by our sense's being hightened and being more in tune with our surroundings. It is believed by some that during our sleep is when the spirit world communicates with us.
