You really want to travel somewhere so your mind is already travelling in your dream. It is high time you planned a trip. Where have you always wanted to go? What places did you dreaming of as a child? Holidays are for refreshments, so book one for yourself.
Dreaming about a postman or a post office signifies that you may soon get some news. It is probably a message that you have been waiting a while for. A “postman” will bring good news, such as news about your promotion or a reward.
