No he messing with your head its a trick , he just wants to Look Good In Front Of his buddys
It means you want him back. Dreams are created inside your mind. They are only inside your mind. That is all.
or it's what you want him to say, causing the dream to have the ex say "i want you back" when really its what you say.
well they say dreams are made of what you desire or fear. and small..very small part of you may want him back. but then again, it's just a theory.
