I love dreaming - especially in that moment just before slumber takes you. That is when my mind runs free and ideas flow. Sometimes I have had to stir from my dreams to capture the ideas so they do not escape into the night.
Last night I dreamed about my NaNoWriMo story. I think in part this was because I had emailed the basic plot to my Alpha editor yesterday and she came back with a myriad of questions. Which was great as I am setting it in the future and there are a lot of different things to consider.
Embrace your dreams and strange ideas, you never know how much someone else will enjoy reading what your mind can create.
