I once had a dream that I went with my family to visit an old family friend (not seen in years) for dinner, but they lived in a different (i.e fictional) house that I had never been to before. Normally this wouldn’t seem strange but when I woke up and told another adult family member, they looked completely shocked. It turns out they had also dreamt of this exact same scenario that night set in the same fictional house. We could describe the setting and events in detail and both had exactly the same experience but from different perspectives in the dream.

I have no doubt there is some psychological explanation for this phenomenon but regardless it was quite an interesting experience.

As someone currently deep into Nix (even contributed to nixpkgs), I’m currently in the process of migrating away and am planning on just running good old Debian stable with docker compose for my home server. I wouldn’t waste your time learning Nix, it isn’t a transferable skill and totally locks you into the ecosystem.
