To dream that you are acting indicates that you are putting up a front and pretending to be someone you are not in some waking situation.

Physical
You are looking at your personality, how you live your life, and present yourself to the
public. If you are acting, you’re examining the roles and qualities you portray to your “audience” in daily life. Look for tips about improving your performance.

Emotional
If you’re uncomfortable acting, you may feel superficial or
forced to please others. If you’ve forgotten your lines, you may feel
anxiety about a real-life situation. A phenomenal performance means you are showing yourself how to be uninhibited and unselfconscious.

Spiritual
You’re ready to expand your self-expression, experience more joy, and allow the
energy of others, your audience, to
help you be your most dynamic self. You are exploring the idea that you can understand anyone by
walking in their
shoes.

You must assert yourself in a more positive way to gain your ambitions.
If your dream involved meeting actors or actresses, be careful not to repeat gossip or you could lose a friend.
