To dream of participating in a talent show is a message to get to know yourself a little better. You may have hidden talents, skills, or gifts that could benefit yourself, family, or community.
To dream of watching a talent show unfold is also a reminder not to take yourself or your loved ones for granted. Everyone has something special to offer, even if they don’t know it yet.... Dream Symbols and Analysis
To dream that you are taking part in a talent show, indicates some feelings of insecurity or trouble with expressing yourself in real life.
The attitude and behavior of the audience will also guide you in how you think others perceive you. (If they act rowdy and boo, you are quite insecure; if they cheer for you, your self-esteem is improving). This dream also reflects your need to be the centre of attention and win approval from others. Also see “Beauty Pageant” and “Karaoke.”... My Dream Interpretation
