Oh yeah. I remember one run directly horizontal from the panel. Had to disconnecti it by more or less gutting the panel, The loose ends sticking out of the wall were taped up with band aid which eventually got loose and fell off. In this appartment there were at least 3 wall sconces per room, all switch controlled, which means the walls were literally plastered with switches, we had no idea what they were used for. Some of the switches and receptacles were of a tiny italian type, I have absolutely no idea why.
One of the lights was wired as follows: 3 wires (switched phase, unswitched phase and neutral) up to the ceiling fixture. 2 wires continuing all the way across the ceiling and down the other wall. Going to the bedside lamp, then spliced to 0.5mm2 LV zip cord, spliced to 1.5 mm2 wires, feeding a RECEPTACLE!
