To see a blueprint in your dream, indicates that you need to pay closer attention to the details before proceeding with some real-life plan or relationship. It may also mean that you are in the process of going through some inner changes in your life. You are working on expanding your way of thinking.
An outline of your goals and plans for the future.
The patterns of your life, the image shown being your conception of what you have built thus far, or that which you hope to build.
Directional guidance for knowing how to proceed with a specific project or concern. Look to the rest of the dream for details that delineate this further, like any symbol key that appears on the blueprints.
