Of course! We have just added the Dreamscape to the biomes page here. While it isn't identical to Purgatoria it holds the similar role of being the true world set over ours which characters can only really experience while dreaming. Most characters have a dream projection there. Jeanne would be able to simply shift from one area to the other. This means that for her any damage done in the dream would be real as it would be to her real body and not a projection.
