  In Judaism, dreams are considered part of the experience of the world that can be interpreted and from which lessons can be garnered. It is discussed in the Talmud, Tractate Berachot 55–60.
  
  The ancient Hebrews connected their dreams heavily with their religion, though the Hebrews were monotheistic and believed that dreams were the voice of one God alone. Hebrews also differentiated between good dreams (from God) and bad dreams (from evil spirits). The Hebrews, like many other ancient cultures, incubated dreams in order to receive a divine revelation. For example, the Hebrew prophet Samuel would "lie down and sleep in the temple at Shiloh before the Ark and receive the word of the Lord", and Joseph interpreted a Pharaoh's dream of seven lean cows swallowing seven fat cows as meaning the subsequent seven years would be bountiful, followed by seven years of famine. Most of the dreams in the Bible are in the Book of Genesis.
  
  Christians mostly shared the beliefs of the Hebrews and thought that dreams were of a supernatural character because the Old Testament includes frequent stories of dreams with divine inspiration. The most famous of these dream stories was Jacob's dream of a ladder that stretches from Earth to Heaven. Many Christians preach that God can speak to people through their dreams. The famous glossary, the Somniale Danielis, written in the name of Daniel, attempted to teach Christian populations to interpret their dreams.
  
  Iain R. Edgar has researched the role of dreams in Islam. He has argued that dreams play an important role in the history of Islam and the lives of Muslims, since dream interpretation is the only way that Muslims can receive revelations from God since the death of the last prophet, Muhammad. According to Edgar, Islam classifies three types of dreams. Firstly, there is the true dream (al-ru’ya), then the false dream, which may come from the devil (shaytan), and finally, the meaningless everyday dream (hulm). This last dream could be brought forth by the dreamer's ego or base appetite based on what they experienced in the real world. The true dream is often indicated by Islam's hadith tradition. In one narration by Aisha, the wife of the Prophet, it is said that the Prophet's dreams would come true like the ocean's waves. Just as in its predecessors, the Quran also recounts the story of Joseph and his unique ability to interpret dreams.
  
  In both Christianity and Islam dreams feature in conversion stories. According to ancient authors, Constantine the Great started his conversion to Christianity because he had a dream which prophesied that he would win the battle of the Milvian Bridge if he adopted the Chi-Rho as his battle standard."
