Dreaming about gambling money in a casino indicates that there are friendships being formed which are not recommendable and that the dreamer is getting involved in an environment which has a very low morale, and this would entail unpleasant results. Dreaming of playing in a casino and earning money that others are losing insinuates that the dreamer wants to enjoy life at the expense of others, but if the dreamer is the one who loses and the other people win, then this indicates that the dreamers failures are consequences of his or her bad behavior.
