Save Points are used in the Silent Hill series as a tool to save the player's progress during the game. They change form and appearance in each game, and there seems to be an important meaning behind each one of them.
|“|| Someday, someone may experience these bizarre events. Hopefully, they will find my notes useful.
In the first game, the player can save their progress in the game by finding a notebook with a pen. This specific save point can be found for the first time in the Cafe 5to2, just before the protagonist Harry Mason is attacked by the Air Screamer monster. It is possible that the save point takes the form of a notebook mainly because Harry is a writer. A few of these save points even serve the story of Silent Hill 3 as they take the form of memos left behind by Harry for Heather.
Silent Hill 2
|“|| Looking at this makes me feel like someone's groping around inside my skull... It gives me a weird feeling.
In Silent Hill 2, the save point takes the form of a small, bright red rectangle, and is the same size as Mary's letter. It can found for the first time inside a well, in the beginning of the game. At first glance, it looks like a simple, red sheet of paper, sometimes stuck on walls. It may represent that James Sunderland can only think about Mary and her mysterious letter the entire time he's in Silent Hill. He appears to show some discomfort and an intense pain in his head when he stares at it.
By the end of the game, James will get his last chance to save the game, with nine red papers stuck on a wall. The guidebook says the final save point has to do with James's memories no longer being repressed.
The number nine is associated to the treble faculties of three. Thus being, the nine save points could represent the Seal of Metatron, as a central triangle inside in a circle forming two more triangles in each side, if taken into account that there are two printed images of it on the rug in the chamber where the last Pyramid Head encounter occurs.
As the paper glows red and features James' head, this may be a reflection of the same dark side in him that gave substance to Pyramid Head. Thus, the pain James feels in his head when looking at it may be the same pain Pyramid Head seems to often display.
Silent Hill 3
|“|| The mark on the mirror... It looks so familiar somehow. Where do I know it from? Where did I once see it...? And... why does my head hurt so much when I try to remember it?
In Silent Hill 3, the protagonist Heather Mason encounters the Halo of the Sun symbol throughout her journey, and it starts to bring up strange memories from her past and from her true self. Heather finds the Halo of the Sun for the first time in a mirror in the women's bathroom at the Central Square Shopping Center. She also appears to suffer from intense pains in her head when she stares at it. The symbol represents resurrection, which means that every time Heather dies, she'll come back automatically, even if that might be very painful for her. It appears in several different places, such as painted on a wall, stuck on the ground or even inside a book.
Silent Hill 4: The Room
Silent Hill: Origins
Travis Grady finds a small, red triangle with an eye many times during his trip in Silent Hill. It can be found for the first time in Alchemilla Hospital while Travis is looking for Alessa Gillespie. Its design and form may represent, in fact, the Flauros and its importance to the game. The eye might represent the watchfulness mentioned in the Halo of the Sun, and Travis, always being watched by Alessa.
