It’s not hard to conclude that the dream Wayne refers to is the Batman v Superman Knightmare, and given hard-to-ignore correlating elements and aesthetics, it seems to conclude that yes, a dozing Dark Knight was given a glimpse into the future of his own timeline and the invasion of Darkseid and his forces from Apokolips.
To do a quick rewind on this morning’s trailer, the specific moment in the Justice League teaser that we’re talking about arrives about one minute in.
Of course, it’s not only interesting to think about the implications of this, but also the question of whether or not the blockbuster will address exactly why it was that Batman had the vision.
Featured as voice-over narrative, we hear Ben Affleck’s Bruce Wayne say, “I had a dream it was the end of the world” — all while footage showcases flying Parademons; a battlefield-leaping, axe-swinging Steppenwolf; and soldiers turning to ash.
