A spiritual test is one that is created from the circumstances around us, perhaps to test our resolve. Having to justify a course of action in dreams might be one such test. Testing something in a dream suggests that there has been some form of standard set, to which we feel we must adhere. This need not mean that we are setting ourselves against others, simply that we have resolved to maintain a certain standard. Dreaming of tests of any sort can indicate some form of self-assessment. Medical tests may be alerting us to the need to watch our health. A driving test would suggest a test of confidence or ability, whereas a written test would signify a test of knowledge.
