I know this isn't a Romanov dream, but it's a royalty dream. I dreamed I was exploring this castle in the mountains in Austria with a bunch of other people. I guess that's how I imagined what Mayerling looked like, but so there's this room at the top and it has a bunch of filthy mattresses, blankets, etc on the floor. It was dark with no windows. The guide said this was the room where Emperor Franz Joseph died, and that we would be sleeping in there that night. I waited a while, and this invisible ghost thing started attacking the other people. That's when I noticed this trap door on the back wall. I opened it and for some reason or another, I shouted "OMG, Sissi killed Franz Joseph!" Then I woke up....
This was a few months ago, back when I had just started getting interested in the Hapsburgs. Later that day, I thought, "Hmmm.... Wasn't Franz Joseph still emperor in WWI?" I guess my brain mixed up Franz Joseph and Crown Prince Rudolph. But until this day, I still don't know why in my dream I said Sissi killed him.
