I don't know that the dreams themselves were real. But we both have nightmares and they combined into something neither of us could handle, and then Ciri woke up and screamed and the monolith on campus broke. I still don't quite know what to think about it.
I suppose if I have some time I could sit down and see if I can... if she'll talk to me? So then I'll know one way or the other. If it even makes any difference.
