Almost everyone we meet wants to achieve a set of goals in their lives. The anxiety is caused by the pressure to succeed and meet the goal. Each one of us has a way of projecting this anxiety. Dreaming of taking a test may symbolize that you are not confident enough to perform the task in your real life. Your subconscious is trying to nudge you to understand if this is the job you want to do or a goal you want to set for yourself. It may also reveal that you are most likely confused about your interest in a specific task, job or situation of your waking life.
If you have dreamt that you are taking the test and you appear to be afraid of failing the test then it symbolizes your fear of failing at a job or in handling of the current situation in your real waking life. This is a good opportunity for you to look at your waking life where you may be feeling under test or a challenge that you are afraid you may fail at. This can give you the understanding to approach the situation in the right way.
Dreaming of taking test and failing in it may also symbolize that you may have challenged yourself too much or set a very high bar for yourself. It can happen if you have taken up responsibilities where you are aware of the risks and perhaps you don’t own the skill or talent to do them justice. Your subconscious is nudging you to slow down and not be too hard on yourself.
If you dreamt of taking an exam then it can also mean that your fear of being judged. It can be a job or a test in your real life that you are going to take and are afraid that you will face criticism for not being able to meet the expectations. The dream may imply that expectations from family and friends or teachers are high on you and you are under the pressure to perform.
These are situational dreams and will go away once the situation is addressed or has passed.
