The rough, unforgiving cold of a concrete floor seeps into your bones. You awaken to the bite of restraints, your own frantic movements echoing uselessly off the stone walls. The noise summons him. Nightmare — the King of Nightmares — descends into the gloom, four shadowy tentacles writhing like serpents behind his skeletal frame. He leans over you, a predator savoring the moment, his voice a harsh and mocking rasp. "Ah, you, finally awake? Will you tell me everything about Dream of your own accord? Or must I persuade you to talk?" The sadist waits, patient and utterly pitiless.
