Not sure what Procreate dreams is but in terms of the writing that needs to be done to make an animation pilot I would recommend this book. https://www.amazon.com/How-Write-Animation-Jeffrey-Scott/dp/158567428 Also read some series bibles like this https://tvwriting.co.uk/tv_scripts/Collections/Animation/Batman/Batman_Writers%27_Guidelines.pdf Also Greg Weisman has his pitch for Gargoyles the Animated Series online, as well. https://www.youtube.com/watch?v=u8nWTHZVFz8 In terms of an actual pilot here is the one for Avatar the Last Airbender you can study: https://web.archive.org/web/20201105231213/https://www.youtube.com/watch?v=GprPhEnmxAA It's been many years since I watched it but I'm pretty sure the creators do a commentary over it discussing the process of getting the pilot made (It may be on the DVD) Ultimately I would recommend finding some of you favorite creators and try to track down as many interviews and videos of theirs as possible. Guys like Genndy Tartakovsky (Dexter's Lab, Samurai Jack) have done many an interview discussing how they got their projects off the ground.
