Dark brown in a dream represents purging of negative thoughts, emotions, habits, and life situations. Some area of your life where you are getting rid of a problem. Unpleasant or undesirable situations are being fixed or improved. Cleansing of negativity. Observing improvements or progress.
Example: An older man dreamed of seeing a woman sitting on a dark brown couch and then going and sitting on the couch beside her. In waking life a girl he knew from his past wanted to get married to him and then he decided to do it. The brown couch may have reflected his feelings about being comfortable getting rid of his single life. “Purging” his life of bachelor style behavior.
The color light brown is symbolic of a genuine desire to get rid of something negative. Good intentions to want to fix a problem or be rid of a problem. Feeling optimistic or enthusiastic about getting rid of a problem.
Negatively, light brown may indicate that you are really sensitive about not being able to get rid of something when you are really motivated to.
