A scenario where I seemed to be at my childhood home, but I was seeing familiar people as if they were another person/character. Not double-vision as much as 'double-meaning'.
For instance, I thought something had happend to Aragorn, so that Arwen had as a matter of course, died (them being so linked, etc.). My mother was somehow also 'Galadriel', and I remember being vaguely surprised she didn't seem more upset. Also was assuming that she hadn't yet informed dad (who was thus also Celeborn. In the book, they were Arwen's grandparents).
