The Opening

As soon as I placed my hand on the fifth tile I was transported into this safe place underneath the linoleum floor. I kept on walking, and then I heard some voices. I could almost make out the words:
"Hanna...across the room...touch 5th tile...Megan."
Oh my god. He was telling Hanna where I was. I broke out into a run. Suddenly, I heard the phone ring from my bag. I stopped, quickly grabbed the phone from the bag, and answered the phone.
"You b*****d!" I barked . I shut it and started to run again. I came across a doorway. Attached to the door was a flashlight. I flicked it on and ran down the long, narrow hallway. I had to run up a ramp. I saw a small opening and ran through it. I couldnt clearly make out the silhouette, and then it hit me.
Right in front of me, Hanna was standing there, knife in hand.
