A dream may offer a unique pathway to a person’s inner world. This article begins by examining the combination of dreams, creative writing, and poetry therapy. The case study gives an idea of a creative writing process combined with the thought of Jungian self-analysis and poetry therapy experienced in Finland in 2011. With the perspective of poetry therapy, this study has its focus in dreams, depicted by words and by metaphors in the images of dreams. The research outlines the possibilities to study one’s inner world and gain insight, by having a dream diary. Dreams are commonly used in the contexts of bibliotherapy, and creative writing, but the topic of this three-dimensional combination has been studied relatively little considering what a popular everyday phenomenon a dream is. This qualitative study provides an example of a fascinating area of research in the field of fine arts activities and therapies. Writing dreams creatively in the context of poetry therapy, can be described as a possibility for self-knowledge.
