Red, brown, and orange leaves laid sprawled on the ground as the last glimmers of fall faded away with the nearing of winter. They fall in order to make room for period of barrenness and eventually, the period of rebirth. Thus, dreaming about leaves may symbolize that change is near and you seek advancement in life. You shed away the old and start anew to improve upon yourself. Leaves falling and then regrowing in the spring is symbolic of death, rebirth, and growth. Although you may have fallen and underwent a period of solitude, ultimately, you will absorb knowledge and be reborn. This will be your period of transformation.
Leaves in your dream may also symbolize contentment and openness towards others. They can be indications of various aspects in your life due to their varying colors.
However, to see only brown and withered leaves in your dream, it symbolizes that you feel hopeless and lost. The plain brown color shows that you feel stuck in phase of forlornness. To rid yourself of this, try to change your outlook by seeing what is causing you to feel this way.
