The Neurobiology of Dreams

Introduction:

Dreams have long fascinated humans, offering a window into the subconscious mind and sparking curiosity about their underlying neurobiological mechanisms. As we sleep, our brains engage in a complex dance of activity, giving rise to vivid imagery, emotions, and narratives that can be both enchanting and enigmatic. In recent years, advancements in neuroscience have shed light on the intricate processes that govern dreaming, unraveling the mysteries of this nocturnal phenomenon.
