Monday's Riddle!

A little thrill for this Monday's Riddle! ~F


CREAAAKKKK....BANG....SLAM...CLOMP, CLOMP, CLOMP....CREAAAKKK...
     "Who's there?" you say to no one at hand.
     "What's that?" you repeat and purposefully stand.
Peering wide-eyed, you sneak from your room, down the hallway and into the gloom. A flickering flame lights your way, keeping the monstrous shadows at bay.
     "Hello?" you whisper into the dark. No one replies, perhaps it's a lark. 
But alas, no, it's not just for fun. The only way out, is to wait for the sun.
In this place, the walls are alive, the portraits are watching, and the ghosts still survive. You must be brave to live here at length, you must be ready and have what it takes. For it is widely known that which lies within, is something evil and thrives on sin.
     "Who's there, I say!" your breath comes in gasps.
Silence...
     "Answer me!" you stammer, about to collapse.  
Silence... A groan... Something stirs in your wake...
     "WHAT WAS THAT!" you scream, your legs start to shake. 
 And then...
Where are you? 

Check back later if you need to get a clue... : )
