It could mean that you have astro travelled together. I don't know what your relationship to the other person is that had the same dream (as I suppose) you had. It is very special, and an indication of soul partnership. remember that your soul partner do not necessarily have to be the opposite sex as you are. If I knew what the dream was, I could have told you what it meant. It could also be a warning of something to come, and therefor given to two people at once to make it a matter of urgency. One must first hear what the dream was, to be able to direct it into one of these two directions: 1) Astro travelling 2) Warning.
