backrooms theory

the reason mary's mom was so crazy and was boarding up the door and being like "they're everywhere you can't go outside" is because there was an entrance to the backrooms near/in/around mary's house and mary's mom found it and it made her a little crazy and no one believed her when she told people about it which is why she got institutionalized after being a seemingly good mom for some period of time

cuz if the backrooms copies locations that are around entrances like how it does with the entrance in the store basement, like we have no reason to believe that mary's childhood home was near that entrance and why would it be so why would the backrooms copy her house like we see it do unless there was another entrance nearby 

and like mary and her mom have a weird ass accent i dont know if she's american

also i think the bacteria/the lifeform is a still life of some non human entity maybe a fly or an actual bacteria or something. thank you
