 The first method that I'm going to mention from the fandom is going into mall restrooms with buzzing lights. So pretty much this theory posits that if you enter a restroom in a mall and the lights are buzzing in there, this increases your chances of being sent to the backrooms when you're inside. Specifically, you have to stay there for 10 minutes and then close your eyes. And when you open them, you'll be on level zero. Another method they say is rarer than that one, but you have to go through an out-of-place metal door. So pretty much these doors supposedly appear to you randomly in a random building. You'll notice them and you'll consciously know that they're out of place. So if you go through that random door, you'll end up in the backrooms. The fandom also posits a really interesting theory that you're most likely to be sent to the backrooms if you're in a space that looks like the backrooms in reality, almost like if there's some sort of connection between them. So if you're in a room with yellow walls and buzzing lights, you're more likely to be sent to the backrooms than if you're not in a room like that.
