Or maybe it's some kind of secret society, like "Eyes Wide Shut," where suddenly you realize YOU are the real exhibit!

There's a superb little known horror movie, called "Society," by Brian Yuzna, on a similar theme. That one is even more creepy lol.

I'm sure your friend just wants to share something they care about, and just got a little pushy and entitled. I guess we all do that from time to time. :)
