Wanna add my 2 cents. My early days were a constant stream of "events." However, I can only remember a few. Some of the "bigger ones." After one particularly bad experience in a public restroom I completely "buried" that episode immediately afterward (went back & played with my friends & never mentioned it to anyone - I was 6) - only to have it suddenly re-emerge when I was in my 30's. Again, I was in a public restroom - doing what you do in there. And the vision of that event came back so suddenly & with such force that I actually turned around to see if anyone was behind me...
And, of course - addressing something else that was said - I also "buried" my reaction to that re-living. Back then that's what I did. I've spent 57 years "burying" the ghosts of the past - and their effects on me.
Not until therapy did I go back and examine - sorta re-live those events. (In a SAFE environment with my T) Quite traumatic & painful. My T encourages that little boy to come back out and tell her how hurt he was back then - and how he's been in hiding all the years since.
And, yes, triggers are everywhere!! To this day, if my wife gets the least bit "annoyed, or upset" about something - even something completely that has nothing to do with me - I'm triggered to run and hide.
Don't know if I answered your question or not. My T tells me the only way out is through... Wish there was an easier way!!

Somebody else told me that when we bury stuff, we bury it alive. Sounds about right... GOOD LUCK!!
