I have an old sentimental silver ring that I love. I dreamt that I was looking for it, amongst a collection of three.
There was one which was definitely not mine; blackened slightly, and too big. I focussed in on another in particular, and examined it's patina, looking for the familiar dents and scratches -- I know the topography of my ring very well.
This one ring, which could have been mine, had deeper cuts and harsher markings. I thought it was my sister's.
I never did find mine, or I woke up. Not sure which.
