As you said, "back to reality". LSD is altered mental states that distorts cognition and perception.

No, I've never taken LSD. Heck, I don't even drink. Never got the attraction. But clearly it exists for the majority of the population, so I'm the odd one.

I'm not proselytizing to be very clear, but there is solid scientific evidence that LSD and other psychedelics can improve mental health in ways that other treatments can't. For exampling, lasting cures for alcoholism and PTSD with as little was one treatment. There is no other treatment that comes close to those success rates. Studies conducted by top flight institutions too. The Swiss chemist who originally synthesized it and ingested it, Albert Hoffman, continued to experiment with LSD and other psychelics throughout his life until he died at age 102. The hippies trying to find enlightenment at Grateful Dead concerts might have been onto something.

Michael Pollen wrote an interesting book about it, and talks a lot about the scientific theories as to why it works. To vastly oversimplify, in controlled settings it can allow your brain to move away from the trauma causing thoughts. For various reasons, many studies have been conducted on terminal cancer patients, who reported lessening or even losing the fear of death. Recommending the book just as an interesting read. Not suggesting anyone should drop.
