Repeated Dreams Regarding Same Girl Each Time

Background information that may be relevant: I am male and 16. This girl is the same age and we went to elementary school together. I had had a massive crush basically until the beginning of this year, even though I probably still do, she just turned into a brat. I transferred to the elementary school in kindergarten and I guess she was the first girl that I really had interest in/she was one of my first friends at this new school, although I had had crushes beforehand. This year (freshmen for both of us) she went to a different school than I but we both took the same train and we ran into each other repeatedly. Beginning of the year we talked every once in a while especially waiting to get on but then as the year progressed she wouldn't even acknowledge my presence if she bumped into me etc. Now onto the dreams, although I cannot remember the EXACT details of the ones I've had the past nights (since I did not believe they were relevant since I thought it would just be one occurrence I can account for this dream, although they were all similar ideas just different places). In my most recent dream we were hanging out at my lake house which is in a separate state completely from where I live during the school year so the only reason she would have been up here would have been if I had invited her or something since it would be incredibly out of her way to just end up at this lake place. Anyways, so somehow she was here which I do not remember, then basically we just hung around together and flirted etc. but we were completely alone out on the front lawn and a bunch of other people were inside (no specific people that I know). And oddly it was as if her earlier personality was in her present self. To clarify, she used to be really nice and she was kind of rebellious, she played bass guitar (I play drums and that was one way we could relate to one another), and she was just all around nice but always teasing, never a complete sweetheart. Then around seventh grade she started becoming much more manipulative and unkind and downright selfish. Then I believe I woke up. SO if this is not enough information just to have a general idea of what it could mean are there any tips for remembering tonights dream (I'm sure it will be just my luck that these dreams stop occurring tonight :/ haha.

I have had quite a few dreams about her again recently and because of the lack of responses I gave up on stating that. However, last night was one that I remember vividly so hopefully that can gain some more responses.
I am transferring schools next year (just to gain some perspective on what the premise of the dream was).
So I am hanging out with someone and were walking and we run into this girl and she looks really sad, shes with another friend also. I ask her how shes doing and she says that shes having a hard time since her mom has breast cancer. So then we start wondering around together and for some reason I saw her mom walking by and we just said hi. Then her and I wandered around some more and we just talked and laughed and she was genuinely happy (which I haven't seen in real life so it was odd) we were both genuinely happy as a matter of fact. Then I put her in front of me and had her stand on my feet and we talked about when we were much younger and such and then I kept wandering with her but the whole time she was hugging me. Then I realized I was going to be late to class and I went out to the parking lot to put stuff away in the car. And I had to ask someone where my class was and it ended up being outside.
This is really starting to freak me out. I even searched her on google images and the first row were pictures of her which I never see if I search a particular name, its always random people. Then out of paranoia I look us up on that love calculator which I always do just for kicks but it was a 98% chance of "success" which I've never seen before, normally I wouldn't think anything of it but this whole dream scenario is freaking me out, because they are all very similar, just different places. Except her mom has never had cancer in any of my other dreams which was random because her mom doesn't have cancer in real life (that I know of).
