This passageway in your dream represents a period of transition in your life. If the surroundings were merry (such as a cruise or holiday), you can expect the future to be much easier than the past. However, if the general atmosphere was one of worry or distress, you can expect some difficulties in making the change. If you walked the gangway, up is, of course, better than down. If you crossed a level one, progress is indicated, but you will first have to cope with some reactivated enmity from the past.
