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.
