Dreams and visions must never take precedent. I'm not saying that you have put the premium on dreams over the Word, it just seems to me to be a needed caution. Without constantly checking with the absolutes of God's Word, the enemy can easily move in. The book of Jeremiah is a good book to read to get a feel of of true messages from God versus false messages one assumes are from God. Dreams and visions are experiences.
Experiences are wonderful.
They are thrilling. The only trouble is, they give little growth to our life. It is a committment to the principles and doctrines of the Bible that bring growth to our lives. A thrilling experience may be the catalyst, but it is the daily learning, obeying and adhering to the doctrines and teachings of Scripture that preserve our life in God and result in growth. Concerning your dreams that give revelations about other people, I think of what one man said.
