A "dream" is a series of thoughts, images, and sensations that occur in our minds while we sleep. These experiences can be vivid and sometimes feel very real, often reflecting our emotions, fears, or desires. People may dream about their daily lives, adventures, or even fantastical scenarios, making each dream unique and personal. Dreams can also serve as a way for our brains to process information and emotions. Some researchers believe that dreaming helps us solve problems or cope with stress. Famous figures like Sigmund Freud suggested that dreams reveal hidden desires, while others, like Carl Jung, viewed them as a window into our subconscious.
