One of my quirks is that I always remember at least one dream. I don't mean always as in once a week, I mean once a night. Some nights I'll remember up to four or five separate dreams, but it's always at least one. I know not everyone remembers their dreams, so one piece of advice is to keep a pad of paper right next to your bed. When you wake jot down a few quick notes, and then look at what you wrote a week later.
This method is wonderful for kickstarting inspiration. Dreams are a fertile ground for creativity, where are muse wanders free to dream and create whatever it will. The novel I'm currently working on, as well as the one after, are both inspired by vivid and different dreams.
So I ask, where will dreams lead you?
