Throughout history and throughout the world, people have reported sexual contact with various supernatural creatures. Many people believe that “sex demons” were born out of the need to explain topics that are generally considered taboo. Usually, unintended pregnancy, miscarriage and promiscuity can cause anger and persecution.
In Brazil and the rainforests of the Amazon Basin, the Boto river dolphin was believed to have shapeshifting powers. It could turn into a very charming and beautiful man called Encantado, or “the enchanted one.” Encantado would take women back to the river, retake dolphin form, and impregnate them. Young women of the region were wary of any man wearing a hat because, according to legend, Encantado always wore a hat to cover up his blowhole.
In many parts of Brazil, it is considered bad luck to kill Boto river dolphins. If you kill one, or in some cases just look them in the eye, it is said you will suffer nightmares for the rest of your life.
