The dream of becoming a ball player and handing the ball over to the opposing side means that he is currently doing his job well. If you were competing with a rival for a job, you’d have a good result for the dreamer. However, even if the ball is taken away or handed over, the progress of what the opponent is doing will also be disadvantageous if the opponent gets an advantage. However, it is only for reference because one dream implies a part of the process rather than a decisive outcome.
