A spiritual challenge in dreams is one which takes us outside our comfort zone. This could show as a dream about a difficult journey for instance, an apparently insurmountable object or a descent into the underground. Ultimately we may find that it is not as difficult as we first thought. We are forced to reassess our attitudes to our own concepts, ideals or deeply held beliefs when we are challenged in any way in dreams. To be challenged in dreams perhaps by someone barring our way or having an argument suggests that we need to know and understand our skills and talents.
If you are challenged to fight a duel, you will become involved in a social difficulty wherein you will be compelled to make apologies or else lose friendships. To accept a challenge of any character, denotes that you will bear many ills yourself in your endeavor to shield others from dishonor.
