I have nothing more to add than what Wildman shared.
The Lord showed me years ago that we could use praise and worship (even music) in Spiritual Warfare to run the devil off.
It saved me.

The 2nd dream basically seems to self-interpret as well, the man tells you what it is about... I wouldn't get too hung up over the "natural" aspects of it, though it may be hinting at a mystery... I have been in places where it seemed God's Spirit dwelt in a great degree.
As he said, this will be God's blessing upon the congregations that truly learn to worship in spirit and truth.
Awesome!!!

We are only now beginning to experience some aspect of this as our local congregation has begun to break away from the traditions of men, lay aside contention, and learn to seek out the ways of God with humility and gentleness toward one another.
