That’s a really sharp question, because I can see why anyone would make the connection. The title 'Dream in Wonderland' obviously echoes 'Alice's Adventures in Wonderland', and it leans heavily on that whimsical, surreal atmosphere. But having read it cover to cover, I’d argue it’s more of a thematic homage than a direct adaptation. It uses the framework of a disorienting journey through a strange land as a metaphor for processing grief, which Carroll’s work doesn’t really tackle head-on. The protagonist, Maya, follows a rabbit-hole pattern after a loss, but the creatures she meets and the rules of the world are entirely the author’s invention—there’s no Mad Hatter tea party or Queen of Hearts croquet game.
It borrows the core idea of logic being turned upside down, but the emotional core feels completely modern and personal. So while Lewis Carroll’s story is clearly the spiritual ancestor, I think calling it 'based on' might oversimplify what the book is doing. It’s standing on those iconic shoulders to tell a different kind of story altogether. The cover art and marketing definitely want you to think of Wonderland, though, which is a clever hook.
