I love to hear stories of these and need some distraction!
One was a house I used to babysit in as a teen. V "arty" parents, walls painted oxblood or black, real animal skulls on the walls and great vast black French windows with no curtains.
The first English dept I worked in. Dark wood, stained glass, coupled with modern "emergency" lighting at floor level as only source of light..... I was always so relieved to get away on a quiet weekend evening and shut the door on the spookiness behind me.....
Yours?
