Alien abductions are cases that involve humans who are taken against their will by entities who appear non-human. The abduction of Barney and Betty Hill, in 1961, is the first recorded US abduction case bearing the claim that the abductors were non-human.
Len Kasten, lead investigator from the National Investigations Committee On Aerial Phenomena (NICAP), defines "alien" as a hybrid being that has no soul, and more distinctly no heart chakra (Anahata). These beings, who Kasten identifies as The Greys (a type of reptoid), have been abducting Humans in behalf of a sinister "4th dimensional" reptilian race. Kasten claims that if these types of reptilians desire to enter the third dimension, they must consume human blood in order to maintain occupancy in the material world. Abductions are usually conducted for harvesting DNA, or other biological materials usually for cloning, hybridization, and reproduction agendas. Abductions are also a proponent for Human trafficing. The Saurian type reptilians are often mistaken and clumped together with these "4th dimensionals" by anti-Draco activists. John Rhodes, founder of Reptoids Research Center explains the different varieties of reptilian in relation to Earth, in his 2017 interview with Coast To Coast AM (2nd hour).
