In spiritual terms, a qualification suggests that we have been invested with a particular quality or ability. This suggests effort on our part to understand and make use of the hidden meaning in those things we have learnt.
Psychological / emotional perspective: To dream that we have qualified – that is, passed an examination – suggests that we have been tested by an external authority and given permission to use our abilities.
Material aspects: In purely mundane terms, to qualify an action or project is to justify its existence. In dream parlance, we may find that tasks or projects that have given us difficulty sort themselves out in dreams and enable us to move forward.
