Here are some points to consider:
* Carroll's background: He was a mathematician and logician, known for his precise and analytical mind. This doesn't typically align with the profile of someone experiencing a psychedelic trip.
* The book's origins: The story is believed to have stemmed from Carroll's real-life interactions with children, his love for wordplay, and his fascination with logic and nonsensical ideas.
* The Victorian era: Psychedelic drugs weren't widely known or used in the Victorian era, and Carroll would have been highly unlikely to have access to them.
It's more likely that the fantastical and surreal nature of the story is a result of Carroll's creative imagination and his ability to tap into the whimsical world of childhood.
While the idea of a drug-fueled creative process is intriguing, there's no need to diminish the brilliant mind of Lewis Carroll by attributing his work to something other than his own genius.
