We have a saying here that when you dream about your tooth being extracted, you should bite your tongue the moment you wake up so the prophecy will not come true - there will be death in the family. Of course that is just a myth but I have been hearing that from the senior citizens. And when you dream of someone who died in your dream, that means that someone who died in your dream will have long life. My husband had been dreaming often about his parents and siblings who are already dead. We don't know if it means something. I just wish that dreaming of a dead person means a good fortune is coming.
