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