Dreams featuring old colleagues often reflect unresolved feelings or memories related to past work experiences. In your dream, the scenario of wanting to defend your colleague suggests a sense of loyalty or a desire to advocate for those you care about, even if you feel hesitant in the moment. This may symbolize your own struggles with self-confidence or speaking up in social or professional situations.

The fact that your colleague corrected the previous speaker and you felt relieved could indicate a sense of validation. It may reflect your desire for fairness and truth in your professional environment, as well as a wish to see others succeed.

Your interaction with your colleague about past work could signify nostalgia and a connection to your previous experiences. It might also suggest that you possess knowledge and skills that you can still apply or share, regardless of the time that has passed.

Overall, this dream could be encouraging you to embrace your voice and assertiveness while reminding you of the connections and competencies you still hold from your past experiences. Consider how you might apply this awareness in your current life.
