I asked my lovely mate Wulfwalker if this had happened to her before. She said that it had happened twice. One time there was a situation in which domestic tensions were high and in the second instance took place after a funeral. In both situations the buildings had "shifted" in appearance, and the shift was tied to the emotional conditions present.
My mate wondered if I had seen my friend's house on some ephemeral level. Perhaps. I could only share that I had the impression that my seeing was on the physical level. My mate shared that I see more than I think. Perhaps.
