Start with something you know. Have a cat or dog? Imagine them as a dragon and tell their story as you imagine it.
Someone at school who gets on your nerves? Make them the villain in your story and do to them in your story what you'd like to do in person. Make their hair turn into gummy worms.
Take one of your dreams and make it into a story.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
