I was in my office, getting water from the water dispenser, when I turned around to get back to my cubicle, I suddenly found myself in this place with yellow walls and just this extremely irritating humming noise. I've walked around a bit, saw nothing but these yellow walls, hearing nothing but my footsteps and the humming noise, and now I'm starting to go crazy. Can anyone please tell me where I am or if this is some sick prank my office coworkers threw at me?
