For all you video gamers out there is it possible to have a lucid dream where you are in a video game world? I have heard that it is harder to dream about this.

Also, what about settings in books and movies? For example, could you have a very vivid dream of attending Hogwarts School of Witchcraft and Wizardry?

These are two ideas that I'd love to incorporate into my lucid dreams. Please reply.

Thanks!
