I've had vivid dreams for a long time, and at some point in high school I got interested in remembering them. Here are my experiences.
Why I'm interested in this
Dreams are a great way to get to know yourself better. Plus, they are a good way to solve problems. Your subconscious mind works in an environment with different constraints than reality, often providing valuable insights. You may know something that you cannot apprehend consciously. I think that it makes you more creative because you get better at listening to different parts of your brain. Plus, you're sleeping anyway, so you might as well make the best of it. :)
