What could this dream mean?

For the past few weeks I keep having this dream. Its not the same dream every time but the same thing happening in it.

Before I tell you, you need to know this tid bit. I have a ring that I wear on my right ring finger 24–7. I never take it off. Its a ring with my birthstone in it that my older sister gave me on my last birthday I spent with her (She lives across the country from me). Every birthday of mine that I get to see her on she gives me a new ring with my birthstone in it.Its kinda her thing.

Ok knowing that here is my dream/s.

I keep dreaming that I am going to lose the ring she gave me. In the dreams I don’t ever lose it, but I almost do. Like I’ll be washing my hands in the sink and the ring will slip off but I catch it right before it goes down the drain. Or another one is I’m fishing and it some how comes off my finger, I don’t notice till I’m packing up to leave and I see the light catch something shining in the crack of the dock and when I look its my ring.

So you see I don’t actually lose the ring but come close to it. These dreams are starting to make me very paranoid about it in real life. The ring means the world to me. Nothing new has happened to me so I don’t understand what the meaning of these dreams could be.

Got any ideas?
