Dream studies, also known as oneirology, focus on understanding the nature, purpose, and mechanisms of dreams. Researchers explore various aspects, including the content of dreams, their psychological significance, and how they relate to our waking lives. This field combines insights from psychology, neuroscience, and even cultural studies to analyze how dreams can reflect our thoughts, emotions, and experiences. In dream studies, scientists often use techniques like EEG (electroencephalography) to monitor brain activity during sleep. They investigate different sleep stages, particularly REM (rapid eye movement) sleep, when most vivid dreaming occurs. By examining dreams, researchers aim to uncover their potential benefits, such as problem-solving, emotional processing, and memory consolidation.
