When something is said in a dream with a noticeable accent or slur- consider what is being and said and by whom for information about what is being dismissed by habit or routine. A waiter with a foreign accent would be portraying the exploration of nourishment and fulfillment in a way you hadn't considered. What other elements about this waiter might provide clues about possible fulfillment in work? Having a neighbor with a foreign accent or meeting a foreigner can represent a more exotic/different side of you that is being developed. If a person is speaking in a dream in an unintelligible sort of way, it can be personifying a way of expressing yourself that is not authentic or not truthful. If the person is intoxicated, you might explore whether drinking is a crutch for your free expression. See Alcohol and See Foreign People and Places.
