In the dream, I was given a ring (which I may actually go out and design for myself) of silver with an inset garnet. Garnet "reportedly also gives its wearer guidance in the night, protection from nightmares" . OK, guidance in the night and protection from nightmares, in a dream. That's a good thing, I guess. (Though I vaguely wonder if it may have been a ruby, which "are believed to protect their owners. Some thought its protective powers were intensified when set in jewelry, and worn on the left side". Also not bad.)
On the New Age-y front, silver is believed to cleanse and remove negative energy. It is also associated with the moon, for what that's worth.
Something to ponder, though not too much. (I'm not going to lose any sleep over it.)
