Most times, the dream is about participation and connectedness to the common goals held by others in your life.
Being a team player and getting with the program are emphasized often in work and family these days. Whichever of the three roles you most identify with determines your self-awareness within the team sport.
Observing from the audience may indicate that you are feeling off the team or outside the action. Observing as a player who does not enter the game indicates that you feel others are ambivalent about your skills, or you yourself may be so.
Being a player shows your willingness to participate in the game. If you have too many roles on the team or do the work of several players, it may be that you are feeling as though people expect too much from you.
Finally, being the coach is a position of leadership, control, and decision-maker for the success of others. In this case, determining how the team did is important to appreciating the message of this dream.
