You wake up in a cold, dark room. You don't have any memory of how you've gotten there.

In front of you is a big, wooden door with a torch beside it. To your right, a mirror - though it's too dark to see your reflection. A bit further is a purple portal, which you can vaguely see a forest through.

Behind you is a small rabbit hole, just big enough to crawl through. To your left is a window with black curtains drawn over it, though no light seems to be coming from it.

What do you do?
