I remember hearing my son get out of bed when he was 6 or 7 , and when I went into his room , I found that he had sleepwalked over to a plastic canister of some sort of building toy ( legos, knex, something) and peed into it. That was the only time I ever saw him sleepwalk although of course, he might have done so without me finding out. And he didn’t need to be cleaned up because he acted just as he would have if he was awake and using the toilet - don’t recall if he pulled his pajamas down or if there was a fly.
Almost 7 years ago, my son had a drinking problem. His liver was affected, he turned yellow, but refused any medical help. After a month, I woke up a little after midnight to hear a terrible sound. He was bleeding out, and I called 911, and I was expecting him to pass, but when it happens you think, somehow he’ll be okay. I kept saying his name as if he might wake and come back. They took him to hospital, kept him in a room for hours, then told me it would be best if they pulled the plugs saying there was no brain activity.
When I was a kid I was convinced that the infernal things were run by demented leprechauns lurking in the nearby sewers, with the aim of maximum carnage, or, failing that, maximum time wasted for everyone going through the thing.
Even today I am still not sure they don’t exist.
On a bit more serious note, my pet peeve there is variable timing cycles for the yellow. Florida typically has very generous ones, 5-6 seconds. In Cleveland I am usually going to stop for them if I can because the cycles here are only c. 3-4 seconds.
Probably the only life experience I’ve had that I, personally, would say rises to the level of a “trauma” occurred after my family moved from Illinois to Wisconsin, when I was 10 (near the end of 4th grade).
I never really fit in at the new school (I was a nerd, I was the smartest kid in the class, I wasn’t at all athletic, most of my classmates were from families who were wealthy, etc.) and from 5th through 7th grade, I was the subject of relentless teasing and harassment from many of my classmates. I loved school, I loved learning, but it got to the point that I dreaded going to school.
Emotionally speaking the most difficult thing I ever dealt with was flunking out of college my sophomore year. That was the only time in my adult life I’ve ever broken down sobbing. Of course from an objective standpoint, flunking out of college is a lot less bad than nearly everything else mentioned in this thread. It took me a few years to get over it and it wasn’t until I finally did graduate 17 years later that I felt some sense of peace with all of that.
I’ve gone through other things that might be traumatic for some people, but didn’t affect me in that way. For example, my parents each died young. I was in my early 30s when they passed. Difficult to handle, but I can’t fairly characterize it as trauma.
Between the beatings and the hate-rape, the death of my father was more cathartic than traumatic. I did experience trauma twice when I was in the U.S.A.F., once when I observed a B-52 D crash while getting coffee for the two people who had just o.k.ed it for take off(it turned out to be an engine defect and not their fault at all), and another time when the base commander wouldn’t shut down the flightline during a storm and I saw a good friend get hit by lightning and killed while checking out the left wing of a bomber.
I almost died while on the streets of Seattle in the middle of winter, and I had an aneurism at the base of my skull a
few years back that the doctors were sure I wouldn’t survive because of the massive brain swelling which they had to cut away a bit, causing me to lose random years of memories.
Not to mention New Coke, vegetarian haggis in a can and the movie “Cats”.
So, which trauma turned your hair purple? 
Nobody should ever have to go through something like this.
(Seriously, though, you’ve certainly had your share.)
