Vomiting in a dream may represent those things in life that cause you emotional stress, repulse you, and make you ill. This dream suggests that you are rejecting a thought, idea, feeling, or circumstance and that fast and, almost violent, cleansing is required. Examine your daily reality and try to identify matters that would cause such a strong physical reaction. Superstition-based dream interpretations say that vomiting in a dream symbolizes reversals; so if you are short of money you may have a stroke of good luck and your financial situation may improve!
