ANSWER: REALITY

 

The eighteen letter tiles correspond to the unencoded letters written in the tile code in the 16-56 hallway (whose key is on the wall in the hallway). Each instruction can be followed by starting at the corresponding rectangle on the floor in the hallway. The instructions (in the order that the rectangles are embedded starting from the west end of the hallway) give the following letters.

JEA → DEAD
PULL → BULLB
FIRE → FOREO

Encoding these letters and taking the upside down version of the encoding if the instructions were given upside down, the shaded sections draw out the answer REALITY.
