I keep having dreams that my boyfriend is getting out of my reach. Its not blatant, like he's literally out of my reach, but that when I try to see him or be with him he won't turn around or things get in the way of us being together.. In reality I feel like I'm slowly changing and my boyfriend and I are slowly falling apart. Is there a connection between the dreams and reality?

No, you're probably just growing apart and reading too much into a dream.
There are no psychics here.
