I hHave listened to some interesting stuff re dream interpretation from John Paul Jackson. The problem with him though is that he only has CD's and classes, no books. I did read one by Jane Hamon called Dreams and Visions that was helpful. One thing that John Paul said that made sense was that 1/3 of our life is sleeping. This is a time that God can reach us by bypassing our normal state of mind and speak to our subconscious mind. Our normal defense mechanisms are down and we are able to receive things that may conflict with our waking understanding. The devil of course can do this too so it is good to be grounded in the word before really understanding what God is trying to say. There are many many examples in scripture in which God has spoken to his people thru dreams. God does not change. The problem is there is not a clear understanding and sometimes it takes research to discover what God has told us in a dream. Many people do not take seriously that God is trying to communicate to us in a dream so many of us lose out in a blessing. God speaks to us in symbols and dreams are full of them. It really is not that hard once you learn the basics. There are pitfalls however, so one must be careful.
 
For example I had a dream last night of a man speaking to me about giving everything away when he became a Christian. I saw him in black and white, the thought came to me, it is 'black and white' clear and literal. He took scripture as black and white, clear cut, no shadow of doubt. So I wake up this morning and the bible turns to Matthew 19:29 "Anyone who gives up his home, brothers, sisters, father, mother, wife, children, or property, to follow me, shall receive a hundred times as much in return, and have eternal life."
 
such a deal.
