The eyes are windows into the soul, providing insights into a person’s deepest feelings and thoughts. The complex process of seeing is made possible by the delicate interactions between muscles, nerves, and photoreceptor cells. Through exposure to light, the eyes not only see the outside world but also have a vital function in controlling the body’s circadian cycle. When we explore the world of dreams, the brain assumes a central role. During the intriguing rapid eye movement (REM) stage of sleep, when dreams take place, vivid and even strange experiences take place. There are several theories explaining why people dream, ranging from emotional processing to memory consolidation.
