I think keeping a Dream Journal is a good idea, especially for people involved in creative arts.
If you keep pen and notebook next to your bed and write down everything you remember as soon as you open your eyes, you'll find that the more consistently you do this, the more details you will recall, including multiple dreams (the one you just came from and the one before it and the one before that). I kept a journal for over 10 years and the insights and story ideas are amazing and endless.
What was truly fascinating were the experiences in the Dream World that would have seemed impossible in this one, yet demonstrated the capabilities of the brain - like being in two locations at the same time, carrying on separate conversations with different people in each one simultaneously, and being able to coherently engage in both without any sense of confusion whatsoever.
Not to mention fun stuff like transforming into other characters or animals, or flying, like living in a Carlos Castaneda book. Even nightmares are compelling when you can remember them clearly. I had dreams of a sort of Zombie Apocalypse, except the zombies weren't killing anybody, they were just everywhere, walking around and carrying on conversations and having parties as though they didn't know they were dead.
The weirdest thing was a series of dreams about these huge reptilian aliens (in my dreams they were like a violent biker gang), who walked like humanoids and had pointy hooked beaks and claws and stood easily 7 to 9 feet tall. It was more than 5 years later I picked up a book called 'Faces of the Visitors' that featured illustrations of various aliens that UFO abductees had described and there was a drawing of a Reptoid, exactly as I had seen them in my dreams.
