I woke from a dream of new-to-me Seanan McGuire music...to find a Patreon message saying there were CDs available!

prophecy!

...suddenly concerned about the part of said dream where my left knee was fucked up

Maybe whatever dream telepathy message she sent you included some feedback from her own knees?

Because I totally believe that Seanan McGuire can walk in the world unwaking and shape dreams as she sees fit.

yeah that checks out

That makes sense yeah
