I don't think I ever affirmed or posed either thing as a firm theory.

I said, if the scene was a dream, then maybe Raven can dream walk (or not).

If dream walking is somewhere in the realm of Maiden Magic (which could very well not be the case) then maybe it could mean Raven is a Maiden.

Which could give a motivation as to why she vanished (or not: maybe she left for another reason).

And open up the possibility of Yang being used to try to lure Raven out, to target her like Amber was (or not).

We really don't have much information to make any solid theorising.
