Speculation: Movies: Batman V Superman Dream Sequence and Justice League Cameos

This is what we know so far:
- Wonder Woman is currently an Antique Dealer
- There will be a dream sequence
- There will be Justice League cameos
What we can concur is that there will be a chance that Bruce will meet up with Wonder Woman and via a mystical ancient artifact from her Antique collection, he will go through a dream sequence like this:

Our takeaway (including the fact that there will be cameos) is that the Justice League will probably make a short appearance in the dream sequence and in the real world.
It also gives us a hint at what is in store for us in the future Justice League movie:
Darksied. Check out the Omega symbol, which is basically Darksied's logoNot forgetting the parademons:
DO YOU SEE THAT? The winged creatures are parademons.
Warner studios has been very kind as to show quite a lot of things in their trailers and tv spots. This also means that there will be alot more in store in the movie.
