The fortune cookie in a dream signifies success and happiness. The situation has been resolved and there are no obstacles in your way. In addition, the person who brought the fortune cookie symbolizes luck and good karma from a higher power.
It could also signify an important announcement from well-wishers from far away whose name is not known at present time but later will be revealed to the dream by means of fortune telling.
If you dream you are eating a fortune cookie, but you can’t read it or break it open. It could be that your unconscious is trying to tell you that you can’t read the future, and you might need to take on a more practical, grounded approach to your problem.
