身穿王室服饰的普通人

I think I experienced an "instant" of lucidity rather than a fully developed lucid dream. I was witnessing an improbable scene in which people who looked ordinary by present-day standards were dressed in royal garments, perhaps medieval ones. I realized—and it was nothing more than an immediate, ineffable recognition—that this could not be my reality and that what I was observing and experiencing could only be unreal.
