I can't remember when a premonition saved me, but I certainly can remember dozens or hundreds of times when I had an irrational fear that something would go badly but it didn't.

Best I got is trusting my gut feeling.

15 years ago we had a blizzard.
I'm driving a company car on a highway.
My boss called me telling me I can go home for the day.
I'm younger and dumb so I tell him I know how to drive so I'm going to finish my last stop first.
Going 60mph in the slow lane. Barely any cars.

Then I see a cluster of five cars going 80mph~ (15 over the limit like people normally do) while tailgating each other.

My Spidey sense freaks out. I lay off the accelerator and just slow all the way down to 40 and let them pass. Don't wanna be near them at all.

Once they're about 200(?) yards ahead of me all of them hit the brakes. Front car slides rotating 90° and gets ping ponged around in front of me Black ice

Hit my brake. Does nothing.
Start white knuckleing.
See the fast lane/brake down open.
I rotate my wheel just enough to start a turn and clear them just in time. All five hit each other or the walls.

Holy shit I'm glad I listened to my gut
Even if you think you know how to drive. Fucking idiots can still kill you.

I mean, nothing life-saving or earth-shattering, and I don't put too much stock in it now because memory's a funny thing in general, but I've had 'premonitions'.

Biggest one was the period when I went to boot camp as a reservist. I had a dream several months prior about a guy saying 'Welcome to [specific base], welcome to hell' in a thick French accent outside of a barracks. I wasn't thinking about joining at the time. After I decided to join, got sent to boot camp and went to have a smoke on my first morning. Lo and behold, members of the Quebequois platoon that arrived the week prior were out there, and take a wild guess what I heard?

Idk, brain's making predictions all the time and sometimes it gets an eerie hit. We don't think about the ones that don't come to fruition as much.
