The fantasy of animation often draws inspiration from realism of life. British author Cressida Cowell would vouch for the fact. Children's author Cowell wrote the popular "How To Train Your Dragon" series of 12 books, which have already inspired three successful animation hits in Hollywood.
Cowell says her fantasy imagination reflects realities of her childhood. "The series is based on a true story."
I don't know if this answers your question or no but I hope it helps a little bit.
