A forest

The chirping sounds grow louder as the door opens into a lush forest with tall trees all around. You pause and gawk at what you see, wondering how the forest could be on the other side of the shed where there's supposed to be a wall. Cautiously, you step through the door into the forest, peering over your shoulder after a few steps just to make sure the shed is still there, in case you want to make a run for it. It is.

You start walking, aimlessly at first, until you find a direction where the forest is getting less dense and you can see more light, so you head in that direction. You're not sure how far you walk, but you realize that you no longer feel tired from the run with Allison. It's not that you've recovered, but instead, you feel completely full of energy and ready for another run.

Eventually you exit the forest and come to a dirt path that looks well used, although you see nobody or any cars in sight. You look left and right, and apart from grass and shrubs, there's no sign of any life. You're starting to think about heading back to the shed, when you notice a huge brown rabbit almost the size of a dog crawl out of a bush not too far away from where you're standing. You watch it for a little bit as it picks at its own fur, until it suddenly notices you and jerks its head in your direction. You jump back in surprise, wary that the animal might be feral and attack you, but it does next surprises you even more.

The brown rabbit blinks, before pushing its two front paws off the ground, and then it stands on its hind legs, coming to the height of a small child.

"Who are you?" it asks.
