**3. A functional perspective on working with dreams in CBT**

Dreams can be useful in psychotherapy. Some approaches, like psychoanalysis, actively apply to dreams, whereas others, like CBT, leave them on the periphery of therapeutic work. Eudell-Simmons and Hilsenroth [26] defined four conceptual functions of dreams in psychotherapy. A detailed description of the methodological issues and the basis of this division are available in the original paper [26]. Due to the scope of the chapter, we focus on the functions of dreams in terms of CBT.
