Where?

I open my eyes and wait for my blurred vision to return to normal before looking around the dimly lit room. I'm sitting on a damp, cold floor in nothing but my underwear and a thin vest. The last thing I remember was taking the last sip of my white wine.

There is a window but it's high up and very small. My mouth is so dry and my legs and head both ache. There's a bed opposite me, why then, am I on the floor. I go to stand up but I can't, I'm rooted to the ground. Why is that? My feet are shackled and chained to the wall. That bed doesn't look very welcoming anyway, it's stained and the pillow looks old and weathered. There is also a single wooden chair and a plastic bowl on the floor next to me. It's hard to make out too much as the light is so dull.

I can hear a noise, but it's distant. I can't quite make out what it is, it's a banging sound but it's sporadic and sometimes I think it's died out completely but then I hear it again.

I realise I am hungry. There's clearly nothing to eat here, and nobody to ask for some food.

Then I hear music coming from up above me, many voices singing what sounds like a hymn. Then I hear a voice from outside the locked door. "Go and fetch her, it's time for the sacrifice."

The door creaks open and I can make out a tall figure. Where am I?
