This is an interesting theory I've seen floating around! Personally, I think it's a really accurate representation of schizophrenia with a sudden onset of symptoms derailing into intense psychosis. I think this is supported by the medication you see with her name on it being used to treat schizophrenics in the time period. 

In the film it's shown that proximity to the backrooms doesn't matter, just the memories of the people who enter it. That's why Clark only has faint impressions of a home since he's known to be a workaholic while the department store he lived in and obsessed over is rendered accurately. Kat and Bobby have their homes and neighbourhood rendered in the backrooms but there's no indication that there's a null zone nearby. 

I also have no idea what the accent is or where it's from. It's been stuck in my head ever since I first saw it.
