So I dreamed that a Serbian military airplane invaded my country's airspace, and it was all up on the news.
Concerns that we were being attacked, confusion, all that. So we tried to tried to send our own plane, to get close and establish radio contact, and figure out what was up. It took a while, both planes were shitty old Soviet models, so not very fast or maneuverable, but they eventually got close enough together for our pilot to ask "what's up, you invaded our airspace".
The response we got from the Serbian pilot: "I know, I'm just trolling you guys. Bye!". And then he turned around and flew away.

If you're Serbian, a military pilot, or especially both of these, please don't do this.
