are you a paramedic or a bouncer or what?

I've noticed this a few times myself. It's kind of an eerie calm that overtakes you, or at least that's how I felt.

The police captain looks like deputy Garcia from Reno 911.

I am like this in very bad, panicky, tense situations. I tend to become very professional, calm, and polite, and laugh a lot of tension off. I would probably be someone making a call like this, as horrifying as it sounds.

Your name, coupled with your knowledge of how people react after seeing dead bodies, disturbs me.

This happened to me. I found my roommate dead from an overdose, and when I called 911 I sounded like I was in a job interview.

It makes perfect sense to me, yeah. Going into an otherworldly state where all your emotions just have to shut off for a while.

Your brain dumps endorphins in moments of extreme fear to give you that slow-motion feeling of detached calm right as you think you're going to die. The survival benefits are obvious for delaying the onset of panic in gruesome or life threatening situations.

Added an endorphins tag.
