Brother Andrew has a couple of books. I like God's Smuggler the best. He's the one that started OpenDoors.
Also, there's the book 'End of Spear' by another person which has been made into a movie. I heard that the book is so much better than the movie. Haven't read the book or seen the movie yet.
I think its not that unusual for people to dream about things that they can't comprehend why they are dreaming such things. Also some may mistakenly think that the dreams are from God. Many I suspect do not know how to overcome them. I think that this website will help. I've not read everything in it but so far it seems pretty good.
