You are having anxiety around being held accountable in some aspect of your life. Quizzes, tests, and exams are part of the structure of education that most people in the West first experience in childhood. This is imprinted in the brain as a permanent memory, associating the sensation of performance anxiety with images of being tested in school. In dreams, these become a metaphor for the ways in which we are tested by challenges in life. We only pass such tests if we have gained a sufficient level of knowledge from past lessons learned. When you dream of taking a test, your unconscious is letting you know that there is underlying anxiety around how prepared you feel to face your life. Examine your life for areas where you feel you are being held accountable, even if the only person holding you accountable is yourself. This is often a recurring dream for people who experience high levels of performance anxiety, a fear of failure, or frequent feelings of judgment from others. It can also indicate a hidden need to be acknowledged by those in authority in your life and to feel validated for your accomplishments. In this way, a test dream can be a compensation for feeling undervalued.
