If you dream dart board with darts, the message can be to practice your skills. If you have competitors or enemies, the dart board has safely captured all the darts and none have shot astray to harm you. You can help yourself by taking precautions.
If you regularly play darts, then dreaming of darts and the dart board does not hold special significance for you. Since you are regularly in touch with this theme, it means your dream has continued with the same theme that you spent time on, during your daytime.
