According to the Heavenly Pattern: The Seer's School on God's Creative Imagination in Bloomington, MN

The seer's mind is like a paintbrush. The seer needs to stir up the colors of their imagination and allow themselves to be a conduit of the message of God. God will use the universe to bring forth his message, and it in very colorful. A seer's imagination will be able to pull images of God's imagery from heaven that we have never seen before. A seer will stand in awe as they begin to project these images and visualizations that come from God. A seer has always had, and will always have these abilities, because the gifts and calling of God are without repentance (Romans 11:29). God has made us co-creators with him, vice-presidents, so to speak! We labor together and we make decisions together with God. God makes the final decisions, because he knows all things, he sees the end from the beginning. He works in all.
