Dream About Shopping Centre Test Error Escalator

So me and my friend Alex decided to go to Blanchard's town shopping centre, this time it actually resembles the shopping centre way better than in my previous dream except it had 3 floors instead of 2. So me and my friend Alex have a test to do tomorrow(in real life and in the dream). We sit in the front left row with seats that have space for writing stuff in a copy. When everything goes black I decide to take my copy out and multi task studying for the test and then the lights turn on. at first I taught that everyone decided that it's better with the lights on, I also did because writing stuff in the dark is hard. But then a error screen shows up on the movie screen and the movie is cancelled. Then I see my friend Ali, then max and Alo sitting in the seats in front of me and me and Alex are laughing that they're here too. We look back and see 2 other classmates in the cinema. My friends and some people are gathered around an employee(getting their tickets returned) Then I leave Alex and go to my friend Dáithí and his friend Jessica is also there too. Me and Dáithí start talking and I'm telling him how the movie cancelled and Jessica tells me that the tickets return guy is at the 1 floor. So I start running the opposite way she was going trying to find an escalator. But then she's on an escalator that popped out of thin air so I start running towards her.
