Putting aside all the theology on dreams, the following is written with the general acceptance that God speaks through dreams and they have relevance (after all any other mindset on the matter is lunacy, right).
So, 2 interesting dreams I had recently;

1. The Comedian Show dream.
I was at some sort of comedians show.  Half way through the set the guy on stage stops and asks the question something like "Who needs Jesus here?"  So some people respond by raising their hands as if in an evangelical meeting.  The comedian then kind of cordinated for anyone present who could pray to get together with these people and pray with them, while he just gets back on with his show.  I went over and prayed with 3 people.  The first guy I prayed for, the Holy Spirit came on him in power and he opened his eyes suddenly saying "God just spoke to me.  He said I've shamed the cross."  I then prayed for 2 ladies.  One also heard God speak to her and she went off somewhere.  The other I counselled for some time and she left her details for follow up contact.
As the comedian did his thing, it was as if God just broke in and spoke through him like he spoke through Balaams donkey.  The important thing was that God's will got done, and he did it without any human organisation.  How cool.
Isaiah 56 "Maintain Justice and do what is right.  My salvation will soon be revealed."

2.  Londonderry outreach
I was part of an outreach to Londonderry, NI.  To return home we went throught some sort of train station/border crossing terminal type place.  As we were in this place one of the team just started worshiping with a guitar and we all just joined in.  I was jumping around worshipping.  It was great.  Other people in the place joined in.
When we had finished a bit of a crowd had gathered.  On of the girls on the outreach asked if she could call people forward for ministry.  I suggested that we did not have time for prayer ministry, but just to give a call for people to respond to Jesus.  She then picked up a mic and just started talking.  When she finished talking I took the mic to do the accept Jesus bit as there was quite a crowd.
Somehow the people had chairs and were forming rows, and John Arnott arrived with a team, and we handed the mic over to him to do a proper service, and the dream ended.

Hmmm.  Seems God is up to something.  Perhaps he is saying he wants to do things in this spontaneous kind of way.  If we will be ready and be those who will wait on him, he will show up in our midst and do evangelism for us.  Thats a good word.
