It depends... Are they good dreams? If so, you probably miss him. Of course, you could just miss being with somebody (assuming you're not, already). Or, maybe your dream bf just represents something else no longer in your life. But, I'm no psychologist. Things really come down to this: if you don't want to be with him, you gotta move on (hang out with friends, do more of what you like to do alone, get a new bf, whatever, eventually the dreams will stop). If you want to get back together, you just tell him that and tell him why, then you guys either get back together or not. And, if not, you gotta move on .... In the end, you gotta live in the real world, so go for what you want and make the most of what you get.
dear, you are subconsciously dissatisfied state.your cravings are pulling you even you feel like to control. these mental manipulations appear in terms of dream. what i guess is you are very passionate and tender hearted.......good day
