Significado dos Sonhos is an Android app by KPDeV that provides more than 5,600 interpretations of dreams. The app aims to help users understand the meaning behind their dreams and how they can relate to their waking life.

The interpretation of dreams has been an important part of ancient societies such as Egypt and Greece, where dreams were believed to be a form of supernatural communication or divine intervention. In modern times, various schools of psychology and neurobiology have offered theories about the meanings and purposes of dreams. One of the most important publications in this field of study was Sigmund Freud's "The Interpretation of Dreams."
