Original Description:
You are entering a world of dreams. In dreams, anything is possible. You can travel eons in a single moment. An office can contain an ocean. A factory can construct an entire universe. Nothing means what you think. Laws of nature, and physics, go right out the window.
So how do you prepare for such a world? It's not logic that will save you, but rather your deepest subconscious. This is the place where intuition lives. To help you access that place, we've prepared a series of preparatory challenges. These challenges were created specifically for the Web. If you can succeed here, then you stand a good chance inside Obsidian itself.
