A question about a dream and a girl

Not sure if I should post this here or in dream interpretations, but there was definitely something more 'beyond dreaming' about this dream.

To be honest, most of it is in an out of place blur right now, but I'll recount the moment that really mattered.

I'm in college, and in the dream I was at a party. This party was nothing like any that are at my college, it reminded me more of the house parties we had back home in high school, but in my dream I was definitely aware that I was in college. There was a girl there, quite pretty who I recognized in the dream as a good friend (except I have no idea who this girl is... here face is a blur now, but I know that I have never met this person in my life, but in the dream it was like we were amazing friends and almost even ready to take it to another step - college-type relationship wise, nothing super serious). So now, I'm suddenly in my dorm room, and the party seems to have followed. In the dream my dorm is much bigger, brighter, livelier. So, I'm on my bed and this girl walks over with another girl. They both sit down and as the girl is saying "hey let me introduce you to my friend, X (I'm not going to name this person as I know the name and it's a real person I know). As soon as they sit down, my heart stops in the dream as I recognize that X is my high school crush. She looked gorgeous in the dream (as I think she does in real life). We mentioned that we already knew each other and the girl who brought her over kinda smiled/grinned and left us alone. We start talking, getting kinda touchy/cuddly. This part is extremely vivid in my dream. Now there is a blur in what happened. But after, we both lean in and are about to hook up when I wake up (I am not sure if it was my alarm or by my own accord, I don't remember). When I woke up, I was pretty out of it.

I was not lucid at all during any of this, I completely thought it was all real in the dream.

Some questions, who could that girl at the beginning have been? A DC/a spirit guide telling me that I need to try and reconnect with this girl from high school?
Also, why did the dream end before anything really happened between us? When I woke up I had the feeling that the dream would have ended well and we would have been together... but obviously my brain woke me up before anything between us really happened...
Why did I not become even a little bit lucid? Did I 'give in' to the dream because my crush was there? or that other girl? The stuff occurring was pretty bizarre, the sudden shifts in location, the blurry moments that I can't recall, where we were, etc.

Thanks for any help. And thanks for reading. Just one of those dreams that you need to get off your chest and write down!

Another dream tonight. Actually two. A different girl in both.
The first dream could possibly have been the same girl from my first post, but I'm not positive. The second dream was DEFINITElY a totally different girl. And also someone I don't know in real life at all.

In the first dream, I am a policeman for some reason. But I'm still my age and I'm in my own car. It was like I just passed the police exam or something. There is a backstory to the dream, but I can't remember it. All I remember is that this girl named Alexa drives up beside me on a freeway and I automatically know her. But she reaches into to my car and takes a gun out and tries to shoot me. (in the dream it feels like this has happened before, but in that backstory I was mentioning that I can't recall) I speed away and get on the phone with 911 and explain my situation. Somehow my convo with the 911 operator is very personal, but she isn't someone I know. I get off the freeway and the operator says that Alexa is coming back. I see here, now on a motorcycle for some reason. She pulls up beside me and I start asking "why alexa, why?" She almost blushes, the light turns green and she speeds away in the other direction.

That dream turns into this one. totally different girl here too.

The second one goes as follows: 3 of my friends and I (plus this one girl) decided to go to a club, I was the designated driver. We are all in the club chillin when some people have to go to the bathroom. We all go, and for some reason when we come out of the bathroom we are in my house in LA. I know that my car is still at the club, so we talk about getting a cab back. My 3 friends are somewhere upstairs in my house for some reason and I am in the kitchen alone with this girl. We start talking and and she somehow knows people in my family, and it seems she knows some of my relatives very well. Music starts playing somehow and we start dancing and getting into it. We end up hooking up in the dream and then I move on to another dream.

There was no real love between us, more like friendship and lust, like a friends with benefits type situation. Not really sure how to explain it...

I had quite a few other dreams that cut in and out between the two I posted, and they were about clubs and bars, etc, but they were much easier to understand. My real friends were in it and stuff, no weird dream characters coming up to me. I had interactions with people I didn't know, guys and girls, but those interactions weren't vivid and really had no meaning other than that I still remember them when I woke up.

Please help me out here!

OK, I'm gonna give it a try, although I'm no dream interpreter by any means. And I can only comment on how this looks to me, without having any knowledge about symbols in the dream and their possible relation to the dreamer. I'm gonna say, that the best person to get a feel what the dream meant is the person dreaming it. Because to me, girls mean nothing, or they are not a dream symbol, but if the dreamer knows this girl and has feelings, it has a different meaning.

Sometimes a dream is just a dream. Is this your lifestyle - parties, girls, hooking up and such? Then this could be just a reflection on your everyday activities without any message. If the girl - your old crush- if you still have feelings for her, maybe you were just thinking of her. Maybe you don't want to approach her directly, so you had this another girl to bring her to you and 'introduce you'. If this other girl was a dream guide, I have no way of knowing. If you get lucid, ask her whom she represents.

And sometimes dreams end because we get excited, from some noise, or just the REM has ended. I wouldn't put any meaning to the way your dream has ended.

So I guess you have to think about your feelings and be honest when you give yourself answers about it, even if you don't like them.

Since I'm lucid dreaming, I have had regular dreams with DCs. Before, I didn't really notice any interaction with them in my regular dreams. So I guess you could be more aware and you notice things you didn't before.

I'm sorry if this didn't help. Happy dreams :)

Gab, you have definitely helped a lot. I just wanted some perspective on how to look at my own dreams, not as much for someone else to fully interpret. Thanks for that.

I'm going to try and reach out to those girls that I don't know who seem like DCs when I become lucid.
