To overcome the patient's mistrust at the beginning of the analysis, Bergler offers a mechanism for testing intellectually the accuracy of the analyst's interpretation. This mechanism consists in the correct interpretation of a specific type of dream which he calls a 'refutation' dream. The content of these dreams express the 'refutation' of the conflict caused by a decisive analytical interpretation. A number of examples are given from clinical histories. Bergler believes that, if this type of dream is 'prophesized' at the beginning of treatment, the patient will be impressed when it actually occurs.
