This is going to be fairy ambiguous so I apologise but it’s kind of what made this so weird. Last summer, myself and a friend were taking the underground across the city and EVERYTHING was a little bit off. I don’t mean like overtly odd, but just slightly different. There were numerous armed guards who had slightly different uniforms, various dogs on the train and others which I can’t really remember. I know those don’t seem weird by them selves but they’re the only example I can recall, I remember us sitting on the train and feeling extremely out of place. The only was I can describe it is that it felt like we were in the parallel world which was almost identical to ours but had enough differences to make you feel uneasy. The strangest part was after we go off at our stop we both independent brought up how eerie that whole journey was.
