I often dream I'm in high school again. It's all fun until I realise in the middle of the dream: "fuck it! I don't have to go through this, I finished highschool already"
(I didn't quite went to college much)
So it's a relief moment for me and I usually wake up.
The recurring dream takes place in the first year of highschool. So it's like the feeling of the eternal adolescence beaurocratic rite of passage through an institution. Because, in the dream, I have all other years ahead to live.
Like realising you don't necessarily have to live through it because you accomplished it already!
It's a relief, a really big dreamy sigh and a let go of some tension.
Yes, I agree it's a PTSD reaching a climax and a release.
We were all young and innocent and, being somehow locked up, funnelled through meshes of institutions, moulded, equalized....
We don't consciously process it but the anxiety is damn real and it's so common vibration inside schools and colleges that we cannot feel it because it's water to fish. So I realise now.

Hugs and feelings for all
