MANIFESTATIONS OF DELUSIONS

CHAPTER 3
MANIFESTATIONS OF DELUSIONS
...Poltergeists are among these. Negative emotions, like fear, worry, or stress manifest into external energy with physical effects. Nightmares have, in some cases, been shown to trigger them. However one such phenomena doesn't appear to happen to just anyone. Although it's not clear why, adolescents, especially girls, are prone to such occurrences.
I think it is Mary's corpse whom drags James into the other world because the conscience physically exists their. For example, the 67 who died of illness & now rest at the bottom of Toluca Lake most likely pulled the Little Baroness into the other world.
Like Alessa & Walter, Mary can manifest part of her sub/conscious mind, like emotions, personalities, etc. For example, Walter Sullivan manifests his boyhood desire to live w/ his mom & his obsession w/ finishing the 21 Sacraments while his spirit is trying to possess Eileen, Heather subconsciously manifests her obsession of suicide. The same thing can apply to Mary; she manifests her feelings of unsatisfactory to James as Maria. In the case of the Maria ending, Mary manifests yet another kind of sub/conscious element, in my eyes: the desperate feeling of trying to wake up James. I think the real Mary is what you see in about half of the endings, in the bedroom, laying on the bed.
It is also apparent that James seems to be able to sub/consciously influence the other world. Much like Heather after regaining memories also gains more influence over Claudia's other world. Much like Laura tells James she was friends w/ Mary a year ago, James memory begins to change, therefore, he gains some influence the other world. I think the same thing can apply to the Mary/ia battle, James ultimately realizes the truth & his main goal, influencing Mary/ia's image.
In addition, I think it's plausible that perhaps Thomas Orosco [possibly her brother too] is responsible for dragging Angela into Unreality.
Laura is dragged in by Mary for some purpose [overwhelming possibilities]. Eddie is somewhat of a difficult case to dictate. It's possible either he was accidently/ purposly dragged in by Laura/Mary or doesn't enter Unreality until he begins his murder spree in Silent Hill.
To summarize: Mary is a parable to Alessa & Walter, for James at least.
