To dream of a car accident signifies turmoil. It seems you are going through some sort of turmoil or conflict because of your writing. Also, the man and woman could be different aspects of your self, or some sort of conflict between the left (rational) and the right (female or creative) side of your brain. It seems however, that after some hard work and struggle, you are able to synthesise the creative and rational aspects of your turmoil in a satisfactory manner which brings about a sense of peace.
I hope this helps understanding where you're at with your writing.
Cheers!
