To dream of a taxi cab represents people or situations in waking life that take care of all the work for you. Choices that you feel will get to you to goals effortlessly if you choose them. A direction in life where you are being "taxied" to answers or solutions that you asked for.
Negatively, a taxi cab may reflect choices you are making that you feel will easily solve difficult problems for you if you make them. Thinking you can buy your success with one easy choice. Feeling that you can easily be taken to a perfect outcome by using you resources you feel you can easily afford. Not feeling you have to do anything difficult yourself.
Example: A woman dreamed of a black taxi. In real life she made a number of vacation reservations that she feared she would not be able to make. The taxi represented the reservations she had others take care of for her. The black color of the cab reflected her fear of not being able to enjoy the vacation reservations.
Example 2: A woman dreamed of being in a cab with 2 men she was dating who ended up stealing her watch and leaving the cab. In waking life she felt that dressing up and being pretty would effortlessly help her get married and slowly began to realize that finding the right man to start a family with was going to be more work than she thought.
