Dream analysis is very subjective and requires a lot of background knowledge about the person who had the dream. For example, how did your ex-boyfriend die (murdered, disease, accident)? How were you feeling when he died? How was your relationship with him before and after your breakup etc...
Generally, this either means you care about your ex-boyfriend and you are worried about him in some way, or that you feel he is in some sort of danger.
or
You don't like him at all and you want him totally out of your life.
