A dream journal is a personal notebook where you write down your dreams as soon as you wake up. Recording your dreams can help you remember them better and explore their meanings. By jotting down details like emotions, colors, and characters, you can uncover patterns or themes that might be significant in your waking life. Keeping a dream journal can also enhance your creativity and problem-solving skills. Many artists and writers find inspiration in their dreams. Additionally, it can be a fun way to track your sleep patterns and understand how your subconscious mind works, leading to greater self-awareness and personal growth.
