I had a super weird dream where some friends finally got their dream house; it had just been built, and the yard was stunning. The house was a log house, and somehow the interior was ultra modern. After they moved in they had a house warming party and everyone was enjoying themselves until I noticed the wallpaper was peeling. I tore a chunk off and it looked like really old plasterboard behind it.
A bunch of us starting tearing wallpaper off everything and found that the house was actually super old and run-down, and just wallpapered over, including the exterior. Even the microwave had wallpaper over it to make an ancient one look new (like you'd vinyl a car)
