Michael and Elizabeth Thiessen Interpretation: Pleasant occupations and average income is denoted by a dream of riding in a cab alone; with others, scandal or gossip will plague your footsteps. Driving one may show you are in a dead end job, doing manual labor with no chance of advancement.
It is warning you to find another occupation.
To ride in a cab is to have good fortune. Some Romanis say it indicates that a short but pleasant vacation is coming.
