Dream About Blue Vintage Car And 1970s Era

I was dreaming about getting into a blue vintage car with some random guy. I was in the front passenger seat and we were driving down. Everything seemed so weird to me though. My eyes looked like they had a filter over them even though I could see color clearly. My dream was set in the 1970's, I know this because I asked the guy what year was it, and he told me something like 1975?? Or 1979?? Something like that. When knowing the era, I was excited, but I reminded myself to not get too excited because then I'll be in the waking life. I have no clue if this was a lucid dream or not, but it didn't feel like a lucid dream, but I was a little conscious in that moment. I saw vintage cars, people had better style, there were more young people outside the restaurants and soda places, it was a nice sight to see. In my waking life, I am not obssesed with the 70's, I'm obssesed with the 50's so I have no clue why I'm dreaming about the 70's. Back to the dream, I went inside this place that was made out of glass, and when I went inside, I saw a little boy walking out in suspenders and he seemed to be a five or six year old..and I didn't see his parents around. I don't know what I did inside the store but then I walked out. The next thing I remember is still me being in the 70's and talking to a girl in a school hallway. We were in an outside school hallway. The lockers were blue, school was made out of brick, the floors were cement up until the entrance, but thw entrance was made out of brick and there was a fountain in the middle od the entrance. Students were going back and forth to their lockers and classes and the girl whispered in my ear "ew look at them." I turned to my left side and I saw a girl and a boy talking by the fountain. They seemed to have a lovely conversation because she was smiling the entire time. They both wore varsity jackets and such but the girl wore blue and the guy wore red jarsity jackets. Varsity socks too. The girl that was talking to the boy was holding books and he wasn't, but I can't remember if they had bookbags or not. I do remember the rest of the dream but it seems insignificant to tell it so...help me out. What does this mean?
