In I Dreamt Last Night (1977), Medard Boss explores the phenomenology of dreams, emphasizing their role in revealing the structure of human existence. He argues that dreams are not random or symbolic puzzles but direct expressions of the dreamer’s lived experience. Through careful observation of dream narratives, Boss demonstrates how they disclose an individual’s way of being-in-the-world, highlighting personal concerns, emotions, and relationships. Medard Boss presents dreams as a window into authentic human experience, providing insights that cannot be fully accessed through waking reflection alone.

Medard Boss integrates existential philosophy with practical dream analysis, influenced by his study with Martin Heidegger. He maintains that understanding dreams requires attention to the whole experience, rather than isolating symbols or unconscious desires. By engaging with dreams phenomenologically, individuals and therapists can uncover deeper layers of meaning in human life and existence. I Dreamt Last Night by Medard Boss thus serves as both a psychological exploration and a philosophical guide to understanding how dreams illuminate the reality of human being¹.
