To dream of playing jacks by yourself shows that an inward focus may be beneficial for you at this time. To dream of playing jacks with another is a sign that although it may be rewarding to combine your energies to complete a project, you will still need to be slightly selfish in order to obtain the desired result. To dream of a jack rolling or bouncing away implies a need to settle yourself and remember to breathe deeply before tackling each section of a current project.
