Dreams are a great writing resource. They are the most creative parts of our day. If you are fortunate enough to remember your dream, give it honor and write it down. Who cares if it makes no sense? Don't judge.
What if it does make sense. Better yet. Aren't you glad you wrote down the details? The point is you wrote something and who can claim that you stole their idea? Dreams are ours and ours alone. Use this resource as often as you can. It never has to be seen by any eyes other than your own. Cherish what belongs to you.
You will never run out of dreams. Let your subconscious know that dreams are important to you by endeavoring to remember them. Relish in your own creativity.
