Definitely. Norman Bates is purely fictional. He was created by authors and has appeared in books, movies, and other forms of entertainment to thrill and scare audiences.
In most cases, Norman is not based on a true story. It's more likely a creation of the writer's mind to entertain and engage the audience with an interesting fictional narrative.
George in the George and the dragon story is a knight. He is a brave and heroic figure who is willing to face the dangerous dragon to protect the village.
I don't know who the author of 'the book of norman a novel' is. There could be many relatively unknown authors out there with works that are not widely publicized.
