Chapter 1: What is a dream anyway?

What if dreams aren't what you think they are? What if dreams are really trips into other universes or worlds? What if you stumbled on one that's cursed so you couldn't easily leave it? One person does stumble upon such a world and now must face the prospect of living the rest of their life in this new world. But there's more to the curse than just simply trapping someone. What else might the curse entail? Will this person be able to get back to their own world or will they remain in this new one forever?
