Brave New LA: Aldous Huxley in Los Angeles (2013)

This time in Los Angeles's history from the 20s to the 70s or so is just absurd when you read about all the goings on at the time. Culturally the city was, and still is in many ways, remarkably supernatural. Psychics everywhere, theosophists colonizing the beachwood canyon hoping to form their own utopia, the rise of the self realization fellowship, many cults including Charles Manson's, the early rise of scientology in Pasadena which roped in everyone from movie stars to astrophysicists at JPL. It was all happening at the same time, and most of these groups were taking a lot of psychedelic drugs, often with very wealthy and influential benefactors such as actors or business leaders. And to this day these cults, supernatural groups, psychics, etc, are all still there operating. It is startling how common I come across people in this city who actively see a psychic, or deeply believe in astrology, or are lining up for some meeting at a scientology center, even today.

LA is a big place. There are so many other authors that he might've interacted with such as Ray Bradbury, Larry Niven, and Philip K. Dick. That said, it just so happens that the apartment building he lived in on Crescent Heights just south of Sunset Blvd. also housed many other famous writers including Earnest Hemingway, William Faulkner, and Raymond Chandler. I lived directly across the street from it for two years.

Depending on your state of mind this could go either way. I think you'd need to have totally accepted death and not fear it in order to expire at peace, with or without LSD. But yeah, I imagine it would have been quite a profound final experience before going into the void.
