Strange or weird occurences

Have you ever had a strange or weird thing happen to you, that you still can't understand? Not necessarily spooky, just... unexplainable.

When I was in my teens, I had a secret boyfriend. He was much older than me and would NOT have been approved of.

I used to browse the window of a particular jewellers at this time. Expensive and retro jewellery. There was a ring in the window I always admired but which was way out of my price range. I didn't ever tell anyone about this ring, it was just window shopping.

One day, my secret boyfriend surprised me with a gift. It was 'the ring' (not as an engagement ring, just a gift). Obviously, I loved it, BUT couldn't wear it openly because he was a secret, so I would wear it to bed, but hide it during the day.

One night, while I was asleep, wearing the ring, it disappeared. I searched my bed, my room, the house, but never found it. My bf asked about it and I explained.

I still don't understand a few things about the ring. How did he know THAT ring? I hadn't told him. Had never been to or past that jewellers with him. And where did it go? It vanished overnight without trace.

I am still a bit weirded out by it now. I know the memory can play tricks, but I remember being confused at the time by it all. Unsolved mystery.
