You could write a fanfic from the perspective of the 'monsters' in 'Alice Isn't Dead'. What are their motives? Are they really as evil as they seem? Maybe they are just misunderstood beings caught in a situation beyond their control. By exploring their point of view, you can add a whole new layer of depth to the 'Alice Isn't Dead' universe. Also, a time - travel fanfic could be cool. What if the protagonist could go back in time to prevent Alice from disappearing in the first place? How would that change everything?
To start an 'Alice Isn't Dead' fanfic, you need to immerse yourself in the world. Read some other fanfics to get inspiration, but don't copy them. Notice how other writers capture the essence of the story. Next, decide on the tone of your fanfic. Are you going for a more horror - based approach, or a more emotional and character - driven one? Once you've decided that, come up with a hook. It could be a mysterious statement or a unique situation. For example, 'The radio crackled, and I knew Alice was closer than ever, but something was very wrong.' This will draw the reader in and make them want to read more. Then start building your story around that hook.
