The dream interpretation tells that since balls are equipment for play, this dream imagery suggests you need to play. Perhaps you’ve been hard at work and now your body tells your brain that you need to relax, de-stress, recharge and rejuvenate. All work and no play makes Jack a dull boy.
In reality, the dream metaphor can refer to somebody who is playing ball with you. You might wonder, what kind of ball game is that?
Or in another situation, the ball (action) is in your court and you are the one who needs to decide what action to take.
