I didn’t love school but nothing happened that was bad enough to give me nightmares. I didn’t grow up in the UK, which I think is key here.
There were cliques and mean girls or whatever but none of the real viciousness and violence my British friends tell me was usual when they were growing up. No uniforms.
In PE at primary we had a unit on dancing - we were all taught the twist and some basic rock n roll moves but also encouraged to dance however we wanted. We all got to bring in cassettes of our favourite music to play. And we didn’t have to dance if we didn’t want to. (I was too shy but nobody made me feel weird about it).
No picking teams - we were assigned to teams to avoid precisely this. Nobody made us have showers, but we could have them if we wanted. We could change in cubicles with curtains, or toilet stalls with locks. While none of this resulted in a lifelong love of sports, I did grow up understanding that being active didn’t have to involve being competitive.
It’s desperately sad to think how with a couple of fairly easily achievable modifications school could have been so much nicer for so many people.
(My recurring nightmares are about university. I suddenly realise I forgot to go back for my final year, and it’s been 30 years, and I only have 2 days before my exams, and there’s no internet because I’ve somehow travelled in my current body back in time to 1994. And I can’t find my library card. And I’m not wearing any shoes or socks.)
