Subjective experience, semantics, and machine analysis as a tool
Dreams matter.
This overarching premise, of almost mantric proportions, has historically guided the endeavors of thinkers and scholars striving to understand the nature and workings of dreams. Traditionally, the study of dream content has been situated within philosophy, religious studies, and, later, analytical psychology. However, recent advancements in data science and computational linguistics have disrupted its compartmentalized status. By advancing the study of dreams into the field of computationally measurable observation, where their content is scientifically validated and analyzed using various theories, dreams have gained renewed interest. Today, more than ever, the question arises: Why exactly do dreams matter?
Dreams and Qualia
In his widely discussed essay, "What Is It Like to Be a Bat?", Thomas Nagel discusses the elusive nature of subjective experience. Rooted in our first-person perspective, we are eternally limited by the inability to fully experience the existence of another being. In the philosophy of mind, this subjective experience is known as qualia—a term that encapsulates the realization that while I, as an individual, know and feel my existence, I can only observe and imagine the subjective experiences of others. Just as I will never know what it is like to be a bat (or any other sentient being), I will never fully perceive someone else's dreams. Even if scientific advancements allow us to externalize and replay someone's dreams in a strictly cinematic sense, as suggested in Wim Wenders' science fiction movie "Until the End of the World," the direct experience of perceiving them as our own would forever remain beyond our grasp.
