I could see and I knew that these ships were made out of brass
Brass is an alloy of copper and zinc. It is used when a metal needs to be malleable, low friction, germ-resistant, and low-tarnish.
But if you look at cheap vases made of brass, you see how brittle it can be, with cracks and creases.
The fact that you both saw and sensed it was made of brass is significant. Brass is man-made. Vulnerable, pliable, brittle, flashy, appears almost pure gold.
When people have visions of God's handiwork, it is often seen as clear amber, a gold so pure it is transparent. (Not to say that is the law of dreams or God's way.)
Consider whether this craft might give all impressions of being from God, because it is so immense and beyond our scope of power. Enough that even the elect (represented by you) would not know for sure.
That's a good reason for God to send a dream out into cyberspace.
the names of God written on the craft themselves
Do you think it's possible this was for deception?
Scripturally, God has used enemy forces to allow (painful) purification. Imagine if millions of Christians saw something like this in real life, and jumped on a bandwagon. Eventually there would be a moment of truth where they did not benefit from following, but repented in regret.
It is your dream, however, and it's important that you convey the interpretation true to the source.
