The hidden entrance at school

Date: 12/29/2017

I was visiting my old high school with my university friends and went to the second floor with Steffi. Everyone else went to class. I remembered an older picture of the first floor and it's huge moving walls and dark light but went down the hallway of the second floor. I was in the middle section of the building, the wall to my left had a jungle paint on it, i went to the bigger hallway part and to the left i saw the big windows showing the inner Hof but instead it's a slightly green painted, smaller room with warm light coming from holes at the top and my production prof was there, quickly hurrying out and disappearing upon seeing me. I remember thinking "So these rooms MUST have an entrance", and i tried to find it. I tried finding it by checking out all rooms near that green one which involved me talking and hiding from people and i still felt it being very stressful. At some point, i climbed onto the ceiling of my school and the environment around it changed to some canyon-like place and there were 4 black/gold packages lying in the left of the two door entrance to the room inside school. I first thought these packages were different colored psp cases, but taking up one of them, it turned out to be a black harmonica with golden details that also functioned as a tape player for old songs. That was the third package. The fourth one was basically the same just that it was a slightly smaller piano. I got a notice that going into the room will make me sign up for something i can't remember. I wanted to do it anyways, so i signed up for it and my mission was to go inside the room and quickly get out again cuz of some reason. I opened the two doors and the walls had many holes again that filtered warm light beautifully. I walked down the way with some stairs, squeezed through an opening in the wall and was in the room. I did something and went out where I was informed that i'm allowed to take one package as reward before I continue my missions. I took the harmonica and wanted to try taking the first or second package which was a piece of paper from some alien shop that promised me some kinda bulletprof vest. Before i managed to leave the area, I got a notice that I have to rewards and should leave one if I don't want to get in further trouble with the players, so I left the shop paper. It was more a video game as I remember having checked out another playsave on my device, despite never physically feeling or showing that i'm playing a game, but it must've been a handheld (PSP). This other playsave had a pointy and big, blue ship that u accidentally broke a bit cuz it started on the last save point in the middle of flight. Being back at my save/life i got a standard black ship with cylinder formed parts at the back. I visited some planet with some goddess on it that i had to talk to as an authority person in my new job.
