Will You Play With Madness? Part 3

You grab onto the lock and pull as hard as you can. The rotted wood breaks easily and you find yourself lying on the ground with the lock in your hand. You sit up right as the doors slowly swing open on their rusty hinges.
You walk up and look into the barn. It's very musty smelling inside, a heady mix of old hay and long gone animal shit. As walk inside and your feet leave tracks on the dusty floor.
Aside from the rusty tractor, the barn is mostly empty. You walk past several small patches of hay to the back of the barn where there is a ladder leading up to the loft.
You start to climb the ladder.
The barn didn't look that big from the outside but you climb for what seems like hours and never get to the top. You look down and all you can see is darkness. You look up and see the same. You start to panic and let out a small scream. It is answered by laughter that seems to be coming from inside of your head. Suddenly you are on solid ground encased by darkness on all sides.
You hear the laughter again and the darkness evaporates from around you. It's very gloomy but you can still see. You are standing in what you assume is the barn's hay loft. In front of you is a figure draped in a black cloak. A helmet, adorned by large curvy horns covers his face. In his left hand is some sort of long staff that has a very nasty looking sharp hook on the end.
"Welcome," He says in a very deep voice, "I am the black mage. I bid you sit."
A chair appears out of the gloom and what feels like a hand pushes down on your head forcing you to sit.
"I'm glad you made it this far. Not everyone does." Says the mage. Looking at him, you realize that there's no face behind his helmet. Only darkness.
"Where am I?" You ask.
"You haven't talked to any of the witches have you?" He asks and sparks flash behind the holes in his helmet.
"No, I..." You start.
"Or the mutants? Or the light mage?" His voice sounds angry now. Sparks crackle and pop inside his head. He stands up and pokes the hook into your ribcage. "TELL ME!" He bellows.
"No, I haven't, honest..." You sputter. The mage laughs and sits back down.
"It's just as well. I'm more powerful than any of them, I would have found out eventually."
"Where...where am I?" You ask nervously. The mage laughs again, harder this time.
"Oh, don't you know? Haven't you figured it out yet? Silly boy you are. You're inside your own brain!" He laughs again, so loud it makes your head hurt.

What will you do? There doesn't appear to be a way out of the loft so you'll have to say something to the mage or ask him a question. You could try attacking him, but I wouldn't advise it...
