To dream of a racetrack is a caution to keep your options open. Putting all your energy into one project could unwittingly remove the focus from another project that may be more beneficial for you at this time. Keep your energy clean and ‘back more than one horse.’ This is possibly related to career choice.
To see a racetrack in your dream, represents life in the fast lane for you.
The tracks may be a metaphor for your quest to get ahead in life. Alternatively, you may feel that you are going in circles.
