Weird school escalator

Date: 8/5/2019

I was at some station im guessing Forest Hill but it looked different. I was meeting Chiara there and then she went her way and I went my way. I went down the central escalator and it was very packed with so many Sydenham girls coming up from it. As I was going down the escalator it was quite dark but still so many girls coming up and a few coming down. I had reached the end of the escalator and where going through a couple white doors and corridors when I open one and it was dark. As I walked in the lights blinked on and Mr Guest was standing in the way blocking the access and on the floor was a light pink puddle with worms crawling about. I freaked out and moved out the way. Mr Guest wouldnt let pass through so I had to take a different staircase. In this stairway I met Samiha and her group. We were walking up some flights of stairs towards the balcony. I was wondering why she was there and she told me it was because she needed to go toilet because she busted her lip. We made it to the top and I walked with her arm in arm telling her that I took the escalator down. Apparently I had taken the wrong one which headed towards the toilets. We got to the top and took some escalators down to go toilet. It looked like we ended up in the same place again? Mr Guest was sitting at a table with someone and it was the same white stairway but without the worms. Samiha and the group went toilet. I was looking at some table which had figures built into it and was covered in some blue liquid
