To dream of a dressing room represents your attempt to fit in to a new role or situation. Trying new things or trying to find yourself. Seeing how new ideas or opinions suit you in your relationships. You may be developing a new self-image. If the clothes do not fit, it may reflect your feeling that something doesn’t suit you or feel comfortable expressing yourself with. It may also represent your insecurities about something you are experimenting with.
Not wanting to be embarrassed while trying something new in life. Considering making changes to your behavior in private or practicing a new personality in private. Experimenting with new ideas when other people aren’t around.
Negatively, a dressing room may reflect problems being open about changes you want to make. Feeling that people around you are not understanding about new ideas. Feeling stupid faking your personality.
Alternatively, a dressing room may reflect how you are changing roles or personas. Your personal style of expression may be changing.
