I really need someone to help me out with this nightmare I've been having?

I've had this dream/nightmare almost every night for the past 3 weeks. And its all I can think about and I need to know why I keep having it and what it means if it means anything. Any help will be much appreciated.

I was in this house with 3 other girls. Ok so first of all I've been in this house before in real life but I just can't remember when. Also one of the girls was a girl who was 2 years older than me and we went to the same school in real life. Anyways we couldn't get out of the house the doors and windows wouldn't open. And we kept on hearing things coming from upstairs and we were downstairs hiding in all different places. Anyways it turns out that these things that were coming downstairs were all people I recognized from TV shows. The bad guys from TV shows. That we all thought were trying to kill us even though they had not done anything to us.

Then afterwards it would show us outside a house in a neighbourhood I recognize but again I can't picture where. Then it would show me and 2 of the girls not the one I knew from school. In a limousine returning to my house. And it turns out in my dream I'm rich.

And that's about it but it then replays the whole story another 2 times. Then on the 4th night the same thing happens again apart from everyone gets out and I decide to stay in for some reason. And again I'm hiding downstairs and someone comes down. I don't recognize this person but I recognize the personality of like someone I know. We go upstairs and sit on the bed this person is staring out the window with it open having a cigarette and talking to me about people in my life like he knew them. And I was just sort of sat there staring at him.

Then my dream shows me an image of the 2 girls I was always with at my house scared from what happened in these nights and they just go to sleep in my room, completely casually. Then it shows me the image of the girl I knew from school going home then back to me listening to this man talk. Then he starts talking about 'us' as in me and him. Then I woke up.

Well this is certainly a sporadic dream!! I'm kind of shocked no one has responded to this yet.
first of all, did you ever have a relationship with this girl, other than going to the same school? It seems as if you feel trapped (obviously...) but by the choices you've made with people. It may not revolve around this girl or the other girls for that matter at all. It may just symbolize people as a whole. It seems like in several parts of the dream you were either by yourself or you wanted to be. This may having something to do with socializing in general.
Just an idea **

Hey, I found this dream really interesting. That's because there's something right now which your sub-conscious mind is trying to tell you. You see, that man talking like he knows you... Is actually you. Just a different part of you, not one that you notice in your day to day life but he's there. The sub conscious works in strange ways but it's ultimate goal is to guide you.

I know he didn't say much you can remember but the way I interpret it is that if you want to get what want out of life, you need to understand yourself before you understand others. That comes from looking down, deep deep down (staying behind in the house) and facing your fears and your pains because sometimes what we need may lie outside our comfort zone, outside where we feel safe.

Also some of your greatest pains and fears lay in the past. That's why everything is repeated, because if we don't learn from last time, we can always repeat the same mistakes but we can never truely move forward. Moving forward in this dream was when you were allowed to see what you can have after you stayed back.

I'd imagine that's what he's saying, and when you switched back to him it was probably something a long the lines of "Now, I hope you understand" but talking with your subconsious is like throwing crayons and a sheet of paper and hoping you get a nice picture. Maybe at the very least we can see what it was trying to draw for you.

No I just remember she was in the year above me and she dated a guy in my year and I didn't get on with him.
Thank you for replying, I'm not the best and socializing so I will take what you said into account.

@InterSomnia Your interpretation sounds like that's its right to me. So I will focus on that, thank you my mind is at ease now.
