Interpretation 1 — Martha Clarke
In general this is a positive dream related to creativity. The unconscious has been accumulating and processing data and the oneiric scene presents the fruit of this work. It may be a very useful dream in real life to resolve a certain problem or to the development of artistic, intellectual, or scientific activity.
