Cool dreams. Thanks for sharing.
My first thought was the dark fallen angels are falling out of the sky. It's a place where spiritual battles are fought…GOOD vs. EVIL. ((They)) are losing. GOOD WINS!
Need more details from you interpret further…but chew on this in the meantime to see what resonates.
The Book of Revelation describes a war in heaven between angels led by the Archangel Michael against those led by "the dragon", identified as the devil or Satan, who are defeated and thrown down to the earth.[1][2] Revelation's war in heaven is related to the idea of fallen angels, and possible parallels have been proposed in the Hebrew Bible and the Dead Sea Scrolls
In Ephesians 6 it speaks of dark powers in the air. In the second heaven is where spiritual battles are fought.
