If you received a postcard in your dreams, in real life unpleasant news will visit your home much more often than joyful ones. Receiving a greeting card means that your manager will soon be dissatisfied with your work. Receiving an invitation card means that your joyful mood will be overshadowed by unpleasant news from relatives. For a woman, such a dream heralds a quarrel with her husband. If you have a dream that you are signing a greeting card, it means that you are too open with people, and as a result you are often the victim of gossip and deceit. Leaving the card in the mailbox is a carnal pleasure.
