I was possibly not in this dream, I am not sure, the main character of this dream was the Dune character Lady Jessica Atreides, and her & maybe one or more other people were in the desert on the planet Arrakis (Dune).
Lady Jessica & anyone else with her, if there was anyone else, got ambushed by some Fremen, there was a brief fight, I assume that Lady Jessica won because the Fremen accepted her after she proved herself by defeating them I guess.
Paul Atreides, a brilliant and gifted young man born into a great destiny beyond his understanding, must travel to the most dangerous planet in the universe to ensure the future of his family and his people. As malevolent forces explode into conflict over the planet’s exclusive supply of the most precious resource in existence, only those who can conquer their own fear will survive.
The word Kralizec does not appear in the Dune saga until the book Children of Dune. It is spoken of both as a terrible fate waiting for humankind in its future and as a rite of passage for the species, an inevitability that would test humankind to its limits but, in the end, leave them with the ability to survive indefinitely within an often malignant universe. Paul Atreides Jihad killed more than 60 billion humans, but the price of Kralizec would be far greater.
