Strange 12v Behavior in '67 GT

I'm trying to get my '67 Globe Trotter ready for a trip and I just noticed that the 12v lights are not working consistently. I just tried to turn on the overhead light, which would not work. The refrigerator light was on, so I assume that the 12v to it was working and the porch light worked. After trying the overhead light and the reading lights several times with no luck, they all started working. Then I switched the lights off and turned them back on--nothing. Then everything was working again. It appeared that the porch light and the refirgerator worked continuously. I'm hoping the trailer is haunted because I would have better luck at a do-it-yourself exorcism than working on the electrical but thought someone here might have a more mundane explanation.

Could be my father has mistaken your trailer for mine…

Seriously, start with the fuses and the fuse junction box. You have a bad connection somewhere on that circuit. Just a question of tracking it down. Don’t assume a fuse is good just because it looks ok. Try swapping the fuse, and make sure all the connections are tight on the fuse holder.

You have circuit breakers in the 12VDC system that may be weak and need replaced. They look little rectangle boxes with two posts sticking out of them. When they get weak they will trip and reset more them they should. You can find them a most auto parts stores. Looks like the last pic.
