Dr. Hari Seldon (Jared Harris) and a small group of believers seeks to preserve human knowledge and save civilization after he predicts the end of the Galactic Empire in this sci-fi series based on the novels by Isaac Asimov.
Brother Dusk did not like that Brother Dawn was found to have genetic flaws & differences & he did not like that Brother Day was going to spare Brother Dawn’s life et cetera, and so he decided to try to get Brother Day & Brother Dawn ashed (incinerated) & replaced with new clones that he would make sure were trained to be like him & he would rule until they were old enough.
This Foundation (Season 1) inspired dream took place on a different planet & possibly in a different dimension with fictional versions of Empire (The Galactic Empire’s Emperor Cleon clones: Brother Day, Brother Dusk, and Brother Dawn) who lived in a very large & tall shopping mall-like building in a palace section of the building.
At some point in the dream, there was a large female warrior / wrestler type woman with light-color skin with blonde hair with a warrior style braids who had to jump dimensions and / or worlds (planets) using a portal that briefly opened on a vending machine after something happened possibly involving one of the Empire (Emperor Cleon clones, who looked older than Brother Day but younger than Brother Dusk, and he looked more like the Troy (2004) character King Agamemnon with darker & shinier & nicer hair) getting unstable.
