Any competition suggests a struggle between two polarities, though in the spiritual sense it is actually a joint effort to overcome a challenge.
Psychological / emotional perspective: To be competing in a dream is to perhaps look for a better performance from ourselves than we have managed hitherto.
Material aspects: As today’s world is highly competitive our dreams may highlight competitiveness in ways that we do not consciously recognize. Dreaming of running a race might highlight such competition in the workplace.
Gives gender - specific: Competition in both men’s and women’s dreams will highlight their area of competitiveness.
A woman for instance might find herself competing against another woman for recognition, whereas a man may simply find himself in competition with all and sundry.
