Cats and switches

I was in some sort of building, maybe a government or tech building. There were other people, this was some sort of tour I think. It was the sort of place where the walls and ceiling weren't finished properly. There was a switch on the wall, and a big opening next to it where you could see a room full of computers and people working. A pink/fushia or maybe red post-it-note sign was by the switch (looked like a light switch) that said "master line" in blue writing (probably marker) and I thought if this was switched off that it'd kill all the lights in the building (not just that area or that room), or maybe kill the power to everything, not just the lights. But the weird thing was that I noticed the switch was in the down position. That would usually mean "off."

The hallway in which I was in had some shelves and a table with stuff on it. There were two orange cats, one on one of the shelves and the other on the table. I asked if the cats were friendly and whoever was leading the tour (or knew what they were talking about) said they were. I approached the one on the table and put my hand out and it definitely was friendly, so I petted it. Then suddenly it put it's paw on the back of my wrist and stuck it's claws into me, and I let go and the cat wandered off. That hurt... stupid cat.

Then I woke up.
