High Weirdness (Drugs, Esoterica, and Visionary Experience in the Seventies) by Erik Davis explores the emergence of a new psychedelic spirituality in the works of PKD, Terence McKenna, and Robert Antin Wilson. I’m super psyched to read this!! Davis navigates readers through consciousness, the hierarchies of their perceived realities, synchronicity, and a plethora of other weird aspects of our human experience that is suggested by these major counterculture sf writers.  Magic mushrooms, flying saucers, the invisible trickster entities of the 70s, SF, what more could you want?
