Still thinking about this... wish I weren't

The yes and no answer... and also a maybe? There are times, like today, the 13th anniversary of Hurricane Andrew... when I know anxiety rages and now added to by a newly named storm only 250 miles away... and I need to go stock up on food (only.) This I can identify easily.
When I'm driving down the road on a sunny day, listening to the radio music, with the top down on my convertible.... and suddenly get to experience heart palpitations and "fear"... wha????? Maybe the music contained a drum roll like thunder...or maybe a comment about storms moving in... or I glanced and saw (but didn't "see) dark clouds on the horizon... or....???? No "knowing" that trigger, not for me, yet.... I am just to the point of recognizing it as being "triggered."
[I was injured during a thunderstorm, long before the hurricane, was evacuating.... but didn't get to... another story...]
