So I tripped and fell onto a wall, and everything went black for a second or two and I felt like I kept falling. Then I landed in this yellow office building, and the lights were on in some places and off in others, but it was completely empty. It seemed old and damp and musty. There was no one else there. I tried to find my way out but no matter where I went it was just more of these same hallways and empty rooms. I couldn't even find any windows.

I walked around for what felt like hours trying to find a way out, but there was nothing. Whatever building this was must be the biggest one in the world. I was worried I might get in trouble for tresspassing for a little bit, but there was no one there. I started getting scared, but eventually I found a fire exit. Wherever I was must've been underground, because the fire exit opened to a staircase going up. And I opened the door at the top and it looked like some kind of parking garage or warehouse. That area was also massive and empty, it seemed endless.

I found another fire exit there and it led me to a massive hotel. Somehow there was a huge balcony with a floor so far down that I'm not sure how it didn't intersect with the previous two floors. The entire hotel was empty, not a soul in sight, every room vacant. Eventually I found a hallway with another fire exit...but there was a pit in the hallway that was too big to jump over! In that place I saw hallways there left and right all the way to the horizon on both sides. I looked up, and they went as far up as I could see as well. I think I might've traveled to the future, because I don't know of any structures like this in our world. Anyway I looked down, and it was the same thing, it appeared to be a bottomless pit with these same hallways all the way down. If you haven't already guessed I was freaked the fuck out at this point, and that's when I fell off and started falling. It never seemed to end, I just kept falling for what felt like several minutes, with no floor in sight. I eventually fell to the wall and landed on the edge of the floor of one of the hallways....and everything went black for a second or two, like it did when I fell into the office floor...and then I landed on the roof of one of the shopping centers near my house! Like wtf?! I looked at a clock, and it was still the same time as it had been before all of this happened. I know they say time slows down when you're afraid, but I don't think they mean 1 minute turns into several hours.

I think this was probably some weird dream but I don't know, I remember coming home and have not "woken back up" since then as far as I can remember. That could also mean that I'm actually still dreaming, which I've suspected all along.

If anyone is able to tell me what the fuck might've happened to me I would appreciate it.

Edit: so I searched up yellow office buildings and found this image, it looks pretty much exactly like the one I was in: https://cdna.artstation.com/p/assets/images/images/042/594/804/large/chris-vogelsang-highrez.jpg?1634921683
