I had more or less the same experience when it was Covid. The streets were empty nobody outside, with everything of what you said happening. Plus all the stores closed and tagged on their wood protection things. It was surreal. The 4-5 « normal » guys I saw weren’t even looking normal with this scene. They were in perfect suits talking at the top of some perfect white marble stairs at the entrance of some federal building. It’s was really looking black and white. Or maybe just black.
