nightmare

So it even has a backstory. A kid was drowned in some bay by a supposed CIA agent and all the history about the kid has been removed. I and some other guys talk with some sailor dude and he exclaims that the "CIA can do anything".
The dream ports me back to some kind of burgershot like restaurant where i am teaching martial arts (most likely, karate). Also, everyone is in the backroom where the actual burgers are made. Near the end somebody asks me "Where do you work?" and i remember saying that i work in some hot dog restaurant. Everyone takes it as a joke.
Now supposedly night has came, me and some of my schoolmates are remaining in the backroom. We see that there are a few uneaten hamburgers left and attempt to eat them. They are way too salty and no one is able to finish them, so we throw them into the trash can.
Suddenly, i have a feeling of danger burst in me (i'd assume everyone else has it too, since they act like me). I take a look out of the backroom (for the first time) and it seems I'm in some skyscraper-like building and the backroom being the only room of our "burgershot". We see some shadow moving towards us (it's dark in the corridors, they dimly lighted tho) and dash towards a lift.
Now this is the craziest lift i have ever seen. It's around the size of a pretty big room, it has paintings, a sofa, pillows and a few cushions. We start moving downwards (we didn't need to press a button) and bright white light starts flashing from behind the door. It doesn't stop and we see a few shadows moving from behind the door (i'd assume, humans). The lift stops. The doors open and all they reveal is a picture of the skyscraper.
The feeling of danger gets even stronger. But others seem to be unable to feel it. They feel sleepy and decide they'll stay here until they wake up. Before i realize what to do, a guy dashes through the picture and ends up jumping out of the skyscraper's first floor window. He lands on some kind of roof (the ones above doors), without any injury. Like 20 meters away from the building there is someone standing. I somehow realize he's someone from CIA. While i'm watching him, he pulls out a gun and fires at the jumpers arm leaving him heavily injured. The CIA agent laughs and enters the building. I jump out the same second.
As I land, the other guy decides to make a run for it. When I land, I jump off the roof and start dashing towards him but before I reach him, the same CIA agent captures him and starts pulling the guy towards the building.
Only now i notice that this skyscraper is build in the middle of a dead forest. Trees have no leaves, they look burnt and weak. There are also some fences with no practical use. They're extremely short (about a few meters in length) and the fence itself is made from slate which is about 2-3 meters in height. I continue running through the forest and as I reach one of the fences i hear the CIA agent talking. He seems to be talking to 2 girls (who look incredibly similar to the ones i left at the building). I seem cornered to the fence. The CIA agent laughs and throws a gun towards me. I decide not to catch it. The agent and the girls are amused by the sighting. I turn my back and jump over the fence and continue my run for it.
The dream ports me near some cinema/cafeteria high in the mountains. I get in the building and notice that it has a lot of people in it. But not only it has a cinema and a cafeteria in it, but also living spots, a gym, studying spots. I enter the cafeteria. It's built like a balcony and has a great panoramic view upon the ground below. It somehow struck me that this is slightly above the place where the kid was drowned. Sudden depression hits me and I want to suicide by jumping out of the balcony. I manage to not do that (would be a bad idea, probably) and I exit the cafeteria. In the corridor I notice 3 of my schoolmates. I feel endangered. They pull out guns that look like desert eagles. I run towards the gym but as I reach it a guy with a broom says
"Is he even allowed here?"
A lot of people turn to look at me. Then my schoolmates run in. Someone tells them put away those weapons. He keeps repeating it until one of them does it. The others concede too.

In the aftermath I remember staying in the same cinema/cafeteria/whatever and talking to one of the 3 schoolmates that were supposed to kill me.

It only now struck me that the cafeteria/cinema/whatever could possibly be a last resort for people being chased by CIA or whatnot.
