Coworker Abandoned Building

This dream was about

I was in a video game and I don't remember the preface of it but I remember following this one kid, who’s one of my coworkers that I rarely ever see, to an abandoned building and occasionally I would go from seeing myself in the video game to seeing myself playing the video game and there was a co-worker with me in the video game and then there was someone else who I don't know playing the video game with me
