Barriers in the dream point either to a challenge, criticism and restriction or, however, to the ability to be found through by problems. Did one bump in the dream into a barrier? If so, one looked for a weakness in the awake life which could stop the progress. The closed barrier – possibly in the level crossing – indicates that we do not make progress on our life trip presently that our feelings on the zero have arrived. If the barrier opens, us look maybe other behind which have reached more than us.
