I read the first couple of Castenada books in my late teens.

Carlos Arana Castaneda (December 25, 1925 – April 27, 1998) was a Peruvian-American author and student of anthropology.
Starting with The Teachings of Don Juan in 1968, Castaneda wrote a series of books that describe his alleged training in shamanism. The books, narrated in the first person, relate his supposed experiences under the tutelage of a Yaqui “Man of Knowledge” named Don Juan Matus. His 11 books have sold more than 28 million copies in 17 languages. Critics have suggested that they are works of fiction; supporters claim the books are either true or at least valuable works of philosophy and descriptions of practices which enable an increased awareness.
Castaneda withdrew from public view in 1973 to work further on his inner development, living in a large house with three women (“Fellow Travellers of Awareness”) who were ready to cut their ties to family and changed their names.

Companions
After Castaneda stepped away from public view in 1973, he bought a large house in Los Angeles which he shared with three of his female companions. The women broke off relationships with friends and family when they joined Castaneda’s group. They also refused to be photographed and took new names: Regina Thal became Florinda Donner-Grau, Maryann Simko became Taisha Abelar and Kathleen Pohlman became Carol Tiggs.
In the early 1990s, Florinda Donner-Grau and Taisha Abelar published two books purporting to describe their experiences with Don Juan and his party. Together with Carol Tiggs, they appeared and sometimes lectured at many of the Tensegrity workshops that began in July 1993, and Donner-Grau and Abelar appeared at book signings and gave occasional lectures and radio interviews as well.
Shortly after Castaneda died, Donner-Grau and Abelar disappeared, along with Patricia Partin. Amalia Marquez (also known as Talia Bey) and Tensegrity instructor Kylie Lundahl had their phones disconnected and also disappeared. On August 2, 1998, Carol spoke at a workshop in Ontario. The remains of Partin, also referred to by Castaneda as Nury Alexander and/or Claude, were found in 2003 near where her abandoned car had been discovered a few weeks after Castaneda’s death in 1998, on the edge of Death Valley. Her remains were in a condition requiring DNA identification, which was made in 2006.
Because the women had cut all ties with family and friends, it was some time before people noticed they were missing. There has been no official investigation into the disappearances of Donner-Grau, Simko and Lundahl. Luis Marquez, the brother of Talia Bey, went to police in 1999 over his sister’s disappearance, but was unable to convince them that her disappearance merited investigation. Their opinion changed in 2006 after the remains of Patricia Partin were identified, and the LAPD finally added Bey to their missing person database.
I didn’t know that stuff about his companions. Creepy!
