This might be a wish-fulfillment dream, assuming the dreamer still has lingering attachments to the ex boyfriend. More importantly, this dream is all about the dreamer's emotions and reveals nothing about the ex boyfriend's feelings. The dream does not predict anything in the future.
It can't be said that your ex boyfriend may never get back with you, but, when you dream of getting back together again it's simply a dream because you are always thinking of getting back together again and the dream doesn't mean you will; time will tell.
This dream strongly suggests that the dreamer has serious doubts about the relationship.
The reason why you still dream about your old boyfriend is because you miss him. you just need to relax and dream about something else which you cant because you cant control your dreams but just think about something different.
get a new girlfriend or boyfriend
It means he hopes that you will get back together, and that he is willing to get back together.
It is obvious you are still in love with your ex boyfriend and hoping to get back together with him or it is wishful thinking that he will contact you and therefore he is on your mind a great deal so it is normal to dream that your ex boyfriend is trying to contact you. If he does not have a girlfriend then out of curiosity contact him and see if he will meet you somewhere. Take the risk.
get over it
The ex-boyfriends in this dream symbolize factors from your past. The dream might be about picking up classes or a job or plans that were dropped around the time that you were with these ex-boyfriends.
If he has a girlfriend, don't go back. He will do the exact same thing to you, that he will have to do to his current girlfriend. Good Luck!
If the boyfriend or girlfriend hold you back from your purpose.
