It's from Capitalist Realism by Mark Fisher.

At the time when he killed himself Fisher was developing the idea of "Psychedelic Socialism" as a potential counter to Capitalist Realism. I enjoyed this discussion of the idea:

As I understand it, the idea is that "consciousness raising" is a necessary component of catalyzing and maintaining the sense of empowerment, hope, and motivation necessary for a social movement to succeed. Although the consciousness raising in psychedelic socialism could literally be psychedelic drugs, Fisher is mostly using that are a metaphor. Consciousness raising could also take the forms like music & art, yoga, religion, ritual, reading circles, etc.

This suggests that things like the New Age beliefs of the Hippy movement, the Pan-African/Afrofuturist symbolism of the civil rights movement, or the rock and roll of the anti-Vietnam protests were not just trivialities. Rather they were essential to the movement's ability to impact the world.

Note: If you search for discussions of "Psychedelic Socialism" or related terms like "Acid Communism", a lot of the discussion that you will find is (not surprisingly) among proponents of drug/psychedelic exploration.

Personally, although I found some of the specifics of their viewpoints a little wacky (and in particular some of them are disturbingly anti-psychology), I found the overall ideas that they raised useful. That is to say: for your average person I think the best course of action is to just "absorb what is useful and discard the rest" when reading their discussions.
