I'm Behind You

This is a writing of pages found in a rugged shack.

DAY 1:  I don't know where I am. It's just a windowless room. I see a door and a table. I walk to the table. A mysterious stubstance is there. It looks like expired meatloaf. My stomach was growling. I'll try a tiny bite. This is good. I quickly ate all of it. The last the thing I remember was me falling onto something soft. DAY 2: My "food" was a green substance with red in it. I heard footsteps from the door. I tiptoed to the door and put my ear on it. I heard talking. All I could make out was, "Don't talk about the room 526. 526? What room is that? I wonder. I ate my food.  (There is indistnct writing all for the rest of day 2.) DAY 3:  A small crack was on the east side of the room.  I ripped at it. It started to break.  I found a note in the wall.  It said: GET AWAY. I ate my food. It was gray slop. DAY 4: I woke up to the sound of whispers and footsteps. I put my ear at the door and started to listen. "Fine, this is the room 526." Are you happy now?" I layed down on the cold concrete, and looked out of the crack. There was no one there. I looked in where I found the note. I heard whispers in the room. DAY 5: Silence. I heard nothing. My ears started to buzz. Hello? I screamed. Nothing. I started banging on the door. Nothing. I started to cry. Huh? OH N- (There is a picture of what seems to be a mask on a bed.) DAY ?: If you find this, you need to run. Oh no, hes coming! HEL- I'm behind you. Look.
