I've had those kind of dreams. I'm not a firefighter, but I was a volunteer in another position where I tried helping people. I still haven't decided how open to be on this forum. I'm usually completely paralysed and cornered somewhere and get asked why I didn't do this or that and why I'd get to be alive. My goal is to do a place and time check when I wake up. My ideal one would go something like "It's (month) of (year). I'm in my apartment. Yesterday I did X and had Y to eat. Tomorrow I'm doing Z to relax. There's a plastic raven on my table. I have my books on the chair next to my bed." and then either read something or curl up hugging my stuffed fox. I don't always manage to do all that, but it's my goal.
