You peep through the keyhole, but having removed the only light-source, you can't see anything. You hold the candle closer to the hole, and just then, a gust from within the locked room blows out the candle. You don't have any matches.
Backing away from the keyhole, you notice that all the lights in the hallway are now out. Patting your way along the wall to find your bearings, you get an eerie feeling; like something or someone is watching you. You hear the sound of chains, and a door unlocking.
You bolt forwards, but run into a wall. You try to back off, but hit another. It feels like the walls are closing in from all angles! As you try to jump out of your obstructions, you feel chains constricting around you!
And the last thing you hear is the cling-clatter of metal.
