Here be dragons

I'm on vacations with my family, the path we're walking on it made to simulate a forest, but it's fake, like an amusement park. We walk between the well integrated attractions, looking around. Other the limits of the fake tree I catch a glimpse of a castle in full gothic architecture, all high spires and graceful arcs, in light gray stones and slab roofs. I décide to try and go there, and my family follow. We push past the fake trees into the remants of a real forest, with moss and ashes everywhere.
On the trail we're following, there's a square tower, with a large wooden door, locked. I easily scale the wall and enter it through a window. It's an house, and I start exploring it. The ground level is a diing room with a dark wood flooring, the furniture old but loved. A rickety staircase, almost a ladder, leads up to a TV room with a large, nest-like sofa taking up most of the room, making it nest-like and confy. On the far wall, there's a opening that lead into a bathroom; I can make out the sink and a tiny bit of shower curtain. I take a ladder to the next level and find another dining room, with armchairs and a big window overlooking the forest. I climb up the wall and end up under the roof in a bedroom; the whole floor is the cushy and confy, and there's a lot of pillows, the whole room in effectively the bed. There are a couple off roof windows, making the room sunny. I try to climb up into the roof itself but it keeps elongating, closing around me and making it difficult to breath and move.
