I can only link to this . It doesnt help explain it much , but its a good JoCo song . <| sep |> It ' s kinda obvious that Flash is somehow comic book logic showing him that future . Then they Snyder , Goyer , Terrio need to make that clearer to us . Because , as is , it looks like the dream Flash ' s arrival just happen to occur near each other . And Superman was working with Darkseid in that future , hence the parademons taking Bruce alive directly to Supes . That still doesn ' t explain how Bruce would be dreaming of them . He has no knowledge of Darkseid , Apokolips , or parademons . Again , if the dream is basically being forcefed into his mind and not him just dreaming , then the filmmakers need to make it clearer that that ' s what happening . As is , it ' s just sloppy storytelling .
