Dreaming of a green, grassy yard is a forecast of personal happiness.
In daily life the appearance of a backyard is usually a reflection on the people living in the house. A neat and well groomed yard, with grass and flowers, usually indicates that people living there are conscientious, caring, and have enough energy to maintain their property.
The yard in your dream may be a reflection of how well you have been able to maintain your internal and external environment.
The backyard points to things that are less obvious and, at times, may be unconscious.
It may also represent childhood memories that hold positive and negative emotions and lead to self-awareness.
If the yard in your dream was a measuring unit, think about what you are measuring and if any growth has taken place.
