When I'm bugging out for various reasons I always think iS tHIS rEAL, OR A NIGHTMARE?? But otherwise, no. I may feel like "we're" in a simulation if I thought that everything was exactly the same everywhere, but I don't think that. Because it's not. I think being in your bubble, and thinking there's no way you could be in a bubble has a lot to do with that "we're in a simulation, bro" feeling people get.
