Sleep needs vary by age
Dreams and nightmares, which often consist of real people, places, and life events, may help the brain consolidate memories accumulated over the course of the day, identifying which ones to retain for long-term memory and allowing the rest to fade. Others argue that dream scenarios allow us to process emotions, mull over problems, or act out fantasies in a safe environment. Regardless of their purpose, dreams appear to be universal, even if some people almost never remember having them. Over time, the information in a dream journal can become more psychologically nourishing as you see the deeper rhythms and cycles of your dreaming-waking existence.
