Why should I keep a dream journal?

Benefits

Your dream recall gets better fast. Like, noticeably within a couple of weeks. Beyond that, there's real evidence that people who track their dreams score higher on creativity tests. But the part most people don't expect is the emotional insight. Recurring themes and unresolved feelings tend to surface in dreams, and writing them down makes those patterns visible in a way that just thinking about them doesn't.
