Nice catch there! If you can see the future in your dreams then it is possible that Bran dreamed he communicated with Ghost and Jon at a future date. Sort of like a greendream that Jojen has. This links in with why future Bran would choose this dream in order to communicate with Jon. In essence, Bran is not changing the future with his time travelling, he is closing loops. If you can see what I mean?
But I still like my explanation better, I think futureBran tapped into Bran in the crypts in order to reach Ghost in a wolf dream that futureBran remembers having, where he sensed Jon was in Ghost at the same time that pastBran was in Summer. Remember in that wolf dream of Jon's it is Ghost that is reaching out for his siblings. That howl is a call to his brothers and sisters and to their partners as well by default. Bran was able to answer it because he too was in a wolf dream at the time. Arya was not, she was in the Godswood at the time. But she still heard the howl.
To add to this up until the his last chapter in Dance, Jon has not had the opportunity to do so either. Bran discovers he can slip his skin in the crypts of WF, where it is so dark he can't see the hand in front of his face. Arya discovers she can slip her skin while she is blind. Jon has never had a period where he's blind in any sense yet. Now that he is either grievously hurt and in a possible coma, or indeed dead, he is finally blind to the outside world. If Jon is going to open that 3rd eye, it is now.
