Why did THAT trigger me?
Your threat system stores things the way a smoke alarm stores smoke: crudely, fast, and with a strong bias toward false alarms over missed fires. It was built for speed, not accuracy. It will never be embarrassed about this.
"But it was such a small thing"
Size is the wrong measure. A cue isn't triggering because it's big; it's triggering because it matches. A three-second tone of voice can carry more information about danger than a paragraph does.
And the more times something happened, the fewer clues are needed to recall it. Repetition sharpens the match.
A tone of voice
Tone is processed faster than words. A flat, clipped or over-sweet tone can match an old warning sign before you've heard the sentence.
Footsteps or a door
Sound-plus-approach is one of the oldest danger patterns there is. If who came through a door mattered once, doors carry it.
Silence
For some people the danger wasn't shouting. It was the quiet before it, or being iced out for days.
A particular phrase
"We need to talk." "Calm down." "I'm not angry." Phrases get stored whole, with the whole night attached.
A smell
Smell has an unusually direct route to memory and emotion. It often arrives with the feeling and no picture at all.
Being watched while you work
If being observed once meant being evaluated or caught out, an ordinary manager glancing over is not an ordinary event to your body.
Someone standing behind you
Not being able to see what's approaching is a physical vulnerability, regardless of who it is.
A room, a light, a texture
Context gets encoded alongside events. Beige hallways, strip lighting, a certain carpet.
A date or a season
Bodies track time. Light levels, temperature and weather are strong contextual cues.
Someone's face changing
Micro-shifts in expression are read pre-consciously. You often react before you could describe what you saw.
Knowing this may not stop it
Understanding a trigger and being unaffected by it are different skills learned at different speeds. Insight belongs to the thinking brain; the reaction belongs to a system that doesn't read. You are not doing this wrong because the explanation didn't switch it off.
