An entity haunting is closely linked to the phenomena of Incubus and succubus,two demons associated with sexuality and impure thoughts.The thoery arose around the medievil period,and was about the obsession with womens sexual sins/frustrations. It is believed that these two little tinkers used to visit lonely women and have surprise sex with her, i think it is best to describe it as, Im not sure exactly which preforms which act, but one would have their way with the women whilst the other held them down, either that or chevy chase still has his invisible man thing,and is a little needy....
