Along the lines of what Thunder Bow is saying, I think it might not be appropriate to keep editing a dream and adding detail. Even though it may have seemed like the same dream, because your life situation is always evolving the dreams were likely different or saying different things. It would be best to write down a dream once as best you recall it, and in particular recent dreams would be relevant to your life now. If you have a similar dream later, write that down as best you can recall what happened on that specific night rather than editing a prior dream.
