What is the meaning in a dream of theater

I was in a theater or an opera house and I remember running in because I knew there was something or someone I was trying to get away from. I think I knew it was someone with a gun or just someone that would hurt me. I hid in the loft but I had a feeling my loved ones were in danger too. There were cars chasing each other outside and overall I had a feeling of dread.

I am a police officer and when I go to visit my school everyone sees me as an adult and I like the adults. When I go into the teachers lounge a friend that I haven’t talked to in a long time is there and we sit down on the floor and talk. While we talk the teachers lounge turns into a movie theater and I leave soon after. I drive home in my car and I go inside and get ready for a night shift of patrolling, my first night of patrolling and when I try to go into the drivers seat I end up in the back seat. I keep going trying to get into the front seat until finally my car turns into a tricycle.

So the dream starts out with me and my group of friends in some sort of hotel/apartment thing. My ex girlfriend is also there who is part of our friend group (we both still have some feelings for each other). As I'm walking through the apartment/hotel room a kid who I don't know walks by telling me him and my ex girlfriend are going downstairs so I'm like why not I'll come. We come to an elevator, but while we are waiting I notice something strange start to happen to my ex gf. She started to morph into a girl version of her ex boyfriend before me who was a real douche bag, which understandably freaked me out a little bit. The dream then transferred to all of us on the elevator. FYI- me and 8 of my friends got stuck in an elevator at the Tropicana hotel in Atlantic City for 2 hours a week or 2 prior. Everybody seemed to know the deal, as if the elevator was going to drop. We all counted down 1, 2, 3, jump and we all jumped as the elevator plummeted down. When I jumped I also held onto a metal bar that was above me which kept me secure. Falling in the elevator created a huge sensation of adrenaline, like being on a rollercoster, but I was not scared just more of a rush. Somehow the elevator shot out of the shaft that it was falling and we hit the ground in a parking lot. After bouncing a couple times and a few big thuds we landed safely in a movie theater parking lot by my house. It was just me and my ex girlfriend now and we walked off as if nothing happened. She then asked me if I wanted to go to some bullying seminar with her, I then said yes, all you had to do was ask and we started walking together. Everything I look up tells me that falling and descending elevators are negative dream symbols although the dream didn't end negatively and I was not scared during the free fall as if I knew already what to do. Any insight to the meaning s of these dream symbols would be greatly appreciated and if any more background knowledge is needed I'm happy to oblige.
