Silent hill 2 Remake - Safe Puzzle Solution (Wood Side Apartment)

The poem is different on every puzzle difficulty, but always contains a mention of 3 specific objects. These correspond to 3 pieces of graffiti that are hidden around the room. The relevant pieces of graffiti are hard to spot on their own, but each one was made with specially reflective paint that shows up in greater contrast in your flashlight's beam. Find all 3 pieces of graffiti, make a note of the numbers on them, and compare them to the lines of the poem. Light: Right 15, Left 11, Right 13 Standard: Right 13, Left 7, Right 11 Hard: Right 13, Left 7, Right 11
