Had a dream that was essentially "suddenly, you're in another world" and that other world was... Animal people.
I wasn't myself but a specific character made by the dream, don't recall details other than being a high school age guy.

Thankfully rather than winding up in a government lab for "study" I was instead placed into a school environment in the form of a
government run school made for the families of government staff and personnel so the security was top notch as were the teachers.
The reason being that they could still study me but in a more humane way than in a lab, I guess at least.
I mean, both peoples being humanoid with advanced intelligence, clothes, tools, etc.
I recall some generic "new kid on the block" type stuff which would be obvious happening for sure, multiplied by my circumstances.
The dream itself wasn't very long or at least didn't feel like it, a lot happened quickly and much of it was very cliche.

Sometimes I'm amused by the way my brain tries to build an at least somewhat believable base for something like that.
Not just someone who manages to hide from the government or is just immediately accepted.

I'm not 100% sure but I have some recollection of the first person I encountered being a fox woman in the woods,
a mother out collecting ingredients or hunting I think.
