I wasn't trying to state that. The idea I'm trying to present is that, since it's a world created by the person's mind, then all laws in that world have to come from the same source, instead of an overriding reality that doesn't care what you think. We already know that the mind can control the Otherworld, so what's the line? What if there isn't one, except for what someone draws for themselves? Essentially, time, space, physics, gravity, etc. only exist because the human mind is familiar with, believes in, and pretty much requires those concepts for itself. But if the person was insane enough to not believe in or need the concepts, are they still imposed on the person?There are things I don't know, Aura, I just have to use the evidence at hand. There's no evidence that being in Silent Hill renders a person impervious to the everyday bodily needs: oxygen, water, food, warmth, and rest. And given that a person remains vulnerable to harm and bound by everyday laws like physics and gravity, it seems illogical that they would defy reality in one area but conform to it in another.
What if Laura, having no frame of reference, simply lost track of time and doesn't realize how long she's actually been in the Otherworld looking for Mary after a non-Leave Ending? She might never realize that a day has ended without a cue from a clock, date, or sky pattern, so she assumes it's simply been "some hours", thus essentially stopping, or atleast slowing, time, and thus hunger, fatique, aging, etc. for her.
