Jack in the Box – A jack in the box is a symbol of resiliency and buoyant high spirits. It is connected to playful, childlike innocence. If you dream of a jack in the box in connection with an endeavor or goal, this is a beneficial omen that you will have good luck in this endeavor, and will receive pleasure and enjoyment from doing it as well. If you dream of a jack in the box in connection with another person, this reflects a trustworthiness about this person as well as a fun-loving spirit. On the other hand, if you have a phobia of clowns, then the jack in the box may be rather a terrifying element in your dream. This reflects your phobia, though, and understanding the significance of this symbol will depend on the causes and nuances of your phobia.
