I think it's possible that The Land Without Colour and Storybrooke are possibly in the book. Why? Because Rumplestiltskin seemed to have been aided by Jefferson to get to Dr. Whale's world in order to bring him to The Enchanted Forest and also Storybrooke does have magic, not to mention it's been mentioned multiple times that Earth has always had magic.

Perhaps each door points toward certain fairy tales, I will do a bit of research and see what I come up with.
