Oneirology is the scientific study of dreams. It's an extensive field of research that quantitatively studies the process of dreaming. It looks for correlations between dreaming and our knowledge about the functions of the brain. It also attempts to understand how the brain works during dreaming as it pertains to memory formation and mental disorders. This is not to be confused with dream analysis, which aims to uncover the meaning behind dreams.
