Dreams can be interpreted in accordance with various conceptions. The 'classical' interpretation is related to real and fantasied experiences. The 'interpretation of transference' appeared later in the development of analysis. The 'subjective interpretation' views the manifest dream as a reflection of inner experiences, or projected externalizations of parts of the dreamer's personality. 'Categories interpretation' relates to the instinctual demands underlying the dream. The concept of 'formal peculiarities of the dream' refers to dreams typical for some people: groupings of dreams, dreams in the form of thesis and antithesis, or questions and answers, and other characteristic forms. What aspect of interpretation to employ depends on the momentary situation in the analysis, the presumed significance of the dream, and the analyst's judgment emerging from his 'freely suspended attention'.
