It was a really vivid but non-lucid dream.
My first dream was me going to school by bike at graduation day. I woke up, fell back asleep after 10min and this is when the following dream started. My friend who goes to another school was at my school by car, he asks me if I would ride along in his jeep. We follow the roads and pass by a broken black car, friend says it's from some weird gang. We hop in the jeep again and keep riding, we see those gangmembers (old white guys) standing on the street trying to talk to kids, we accidently hit one but keep driving. Suddenly we are at a gas and train station from a dream that I had months ago. We move on again, it's late at night and we stop at a circus next to the high way. There are cop cars so we wait outside in the car, my friend wants to sleep a bit so he lays down on the backseat. Suddenly an old really weird guy pops out and tries to get in, friend closes all doors but somehow the guy could open it. We jump out and get our car stolen. Friend wants me to call his mom and tries to hand me his phone but i refuse. We go inside get drunk, walk around the circus. Then we both go to the outside restrooms. I'm doing my thing at the urinal when suddenly a guy starts up a conversation with me. I just try to avoid conversation when suddenly he says: am I right Gregory (myname)? I respond with Yeah yes w.e. I step away but then suddenly it hit me that I didnt know the guy but he knew my name, I pull him to me and ask him how he knows my name but he doesn't respond. Some guy comes between me and the other guy. The guy that knew my name goes through a door walking downstairs laughing and says "you're quite smart aren't you". I try to follow him but he closes the door and I can't open it. I ask the guy that came between us who that guy was, he replied Max. I try to find my friend and tell him that we got to get out of here, he refuses my requests and moves to the outside restrooms again. I try to keep up with him and pass by the bartender, I ask him if he knew Max he replies with Yes but just don't.. And then ignores me. I catch up with my friend try to take him with me while I randomly chug down a beer but he insists on going to the restroom first.. Then I woke up.

Please explain because I'm really mindfcked on how he knew my name but didnt want to tell me how
