Cool. It seems like there is always people in my home dreams too.
That castle, it's s beautiful and in that landscape. I'd love to fly around it, land on the roof or atop the towers. Parkour around the outside walls. Fly up over that body of water behind it and maybe land on the mountain peaks. If the dream lasted long enough maybe explore some of the inside.
I hope in reality they have elevators in those towers now... That would be a lot of foot work getting around that place.
