reoccuring dreams, real life stress

[acatalephobic]

Currently looking for some new insight into some reoccurring dreams my sister has been having for years now. Spoiler for the details: They center around a person she has known since preschool, and for whatever reason there is always some obstacle between them, preventing them from communicating or interacting. The circumstances vary, but the theme is always the same. Whether it's bad weather or bad timing or you name it, they are both in the dream but somehow separated. Now mind you, in waking life this person has been a longtime friend. They shared similar interests, some of the same classes, and a lot of the same friends all throughout highschool. They even tried dating once back then but it only lasted a week because they were just too good as friends, basically . And that was more than a decade ago. Cut to the present where life goes on and they havent spoken in many years but yet she has these dreams. At first I think they just seemed random the way most dreams do, but over the years they persisted, and also became increasingly unrealistic with regard to her waking life. In the dreams relationships were starting to be implied (unrealistic ones) but again there were obstacles...it's always something no matter what the scenario. And then most recently, she had a dream that she was having a baby shower for the baby she and this guy were having together (he is married IRL, btw), and the guy's wife was the one conceiving the child for them. When she told me this, I'll admit I was a little shocked. But I was even more shocked when she told me that the day after she had that particular dream, she saw on Facebook that in fact his wife had just given birth to their second child. His wife is a highschool friend of hers as well, and although my sister knew they were expecting, she did not know when. Coincidence? You be the judge. All I know for sure is that as her dreams have progressed, she has had resulting anxiety carry over into her waking life, particularly during a period a few months back where she was having them on a nightly basis for more than a week. Now, I've had a lot of reoccurring dreams and some pretty gnarly nightmares, but never in such close succession and over a prolonged period of time. Even if that only happens once in a few years, it sounds slightly atypical to me. But of even greater concern to me is the anxiety she is developing around these dreams. I have done my best to remind her that dreams can be unpredictable and unruly, and that dream interpretation is a very personal business...and that in her case there seems to be obvious potential for subconscious preoccupation....nothing so far has helped. The conflict in the dream began with a basis in reality I think, but now that they've become absurd and nightmarish she wishes she could just make them disappear. She doesn't even desire to speak with him, as the dreams might suggest. She has begun to stress the dreams too much, as I see it. This stress seems outside her personality a bit, so I feel compelled to help . In my opinion, no one should start a day out badly simply because of a bad dream. Any thoughts on this, or any advice i could give her would be very greatly appreciated. EDIT: her specific questions are "why do I keep having them, why does the storyline keep progressing, and what do the dreams mean?"
