Silent Hill 4/Fridge

Fridge Horror

 * In Silent Hill 4, Henry was sleeping next to  for two years before the events of the game.
 * The whole Silent Hill series in general actually. We know that some things have to be in the characters' heads and some have to be real. But in many (arguably most) places, it's not 100% clear what's real and what isn't. The monsters being people for example.
 * Exhibit one: Alex Shepherd, the protagonist of Silent Hill Homecoming, is the most athletic Silent Hill protagonist to date. At first, we are led to believe that it's due to spending time in the military. However, it is later revealed that he never was in the military, but that a combination of Heroic BSOD and Laser Guided Amnesia led him to believe he was. A popular fan theory to cover this Plot Hole is that because he believed he was athletic, Silent Hill "made" him athletic. Now, what does that mean for the rest of the series?
