The visions of the future where from an Alternative timeline; one where Superman is an evil dictator or a lieutenant for Darkside since there are parademons and the huge omega symbol.
The Flash [from the alternative TL] was possibly trying to deliver a message to this TL Bruce Wayne through his dreams (?).
IDK, they felt a little out of place.

The movie feels like a forced publicity stunt for the Justice League movie, OMG, it's all so forced!!! And the Batman visions??? WTF WAS THAT?!?!?!?
