So what does it mean to dream of a walrus? Funny you should ask, since according to the The Dream Moods Dictionary, to see a walrus in your dreams means the following:
To see a walrus in your dream, represents your display of dominance in some situation or relationship. You are always on the lookout for anybody who is trying to out-maneuver, out-rank, or out-wit you. Alternatively, the walrus represents your protective shell and thick-skin. You do not let the comments/criticism of others get to you.
For Eskimos and Native Americans in the North, the walrus symbolizes supernatural ability and power.
Now you know.
