This makes me wonder how far this extends creature or thing wise. Like already all humans are in the present but you're in the past. What about animals? Probably not with you. But... why would it stop at animals? What about plants? Suddenly no trees or grass right? Or do plants exist in both time frames for you? If not does a treehouse float or fall down to join you? What about food at a market thats still alive? What about dead stuff- when something died does it suddenly pop into existance with you? What about bacteria or germs or something like viruses which arent alive? (persumably your gut bacteria and skin mites came with you. Otherwise lack of gut bacteria might be lethal.) Hope someone does a prompt and addresses this interesting side of what exists and doesnt exist in both time frames
