I had this dream in the late 90's and the meaning of the dream still eludes me. I actually did have a Post Office box and one night I dreamt I went to my PO box and when I opened it and peaked inside, I saw several pieces of jewelry. I didn't touch anything, but suddenly I saw a vague glimpse of a man on the other side of the box and called out to him. He stood quite and I started to explain there's been a mistake. "My box is full of jewelry and it's not mine" the mystery man replied, "there's no mistake, the jewelry belongs to you" I answered, " no sir, I didn't buy this, someone put it in my box by mistake" the man replied, "there's no mistake. That what you see in the box is yours. It's been given to you as a gift" and then the man vanished. I then slowly began pulling out the pieces one by one. The first piece I pulled out was a blue sapphire 💍 ring, the 2nd piece was a diamond dinner/cocktail ring, the 3rd piece was a diamond wedding bridal set, and the 4th and last piece were two gold pocket watches. I looked in awe at this beautiful jewelry in my hands and was overwhelmed that someone would give me such treasures. END
One of the things I noticed in the dream was all of the jewelry except the pocket watches were mounted on silver or platinum bands.
