Joanna is right. If you want to be sure however you could still try to find out what it means in the next lucid dream. Just ask some DCs what would be the right job for you. Maybe you will get a decent answer and if not then maybe it just didn't make any sense and it was just supposed to tell you that you should get ANY other job in the future
Oh and keep your eyes open in every of your dreams... Maybe there will be some features that give you any hints concerning your job life? You never know.
