Basically, a brazilian farmer called antonio villas boas claimed that he was abducted by an uap in the 50s. His blood was allegedly sucked by the beings using a kind of tube on his chin and was forced to have s3x with a human-like creature, he described her as a pale skin woman with white hair. When they both finished, she pointed at her belly, pointed at him and pointed at the sky with a slightly smile on her face. There were no evidence that this actually happened but the doctor who examined him diagnosed him with a disease caused by radiation exposure and he also found purple marks on Antonio’s chin, where antonio claimed that the blood sucking tube was placed.
Here’s a video and an article on Wikipedia about it https://en.m.wikipedia.org/wiki/Ant%C3%B4nio_Vilas-Boas
