Throughout history, people have sought meaning in dreams or divination through dreams. Dreams have been described physiologically as a response to neural processes during sleep, psychologically as reflections of the subconscious, and spiritually as messages from gods or predictions of the future. Many cultures had practiced dream incubation, with the intention of cultivating dreams that were prophetic or contained messages from the divine. Judaism has a traditional ceremony called “hatovat chalom” â literally meaning making the dream a good one. Through this rite disturbing dreams can be transformed to give a positive interpretation by a rabbi or a rabbinic court.//wikipedia
