A password was required to (big surprise) open the door. At first I guessed "Horizon" or something close to it, which was wrong, causing one of the other guys with me to get extremely angry. And on a site note, maybe it's just the power of suggestion, but as close as I can recall right now, he looked like the guy in the game, who you find in the sewers, that unlocks the park for you. So he carried on for a good 30 seconds, and when he finally calmed down, the little "Incorrect" screen appeared, and down below it, there was a hint. All I can remember of it was that it was the name of an animal specific to the game had the letter "C" in it.
Tried using that, and got told it was incorrect again, causing the other guy to get pissed off and angry once more, and that time when the hint screen came up, it said something like "You really thought that was going to be the answer?"
From there, the game part of the dream ended, and switched into the comic part. Flipped over a page, and saw something that I swear came from a furry one I've seen before, but I could only see the bottom panel, and a speech bubble that said *ahem* "Let's make use of this soap".
Getting sort of angry myself at not being able to find out what was behind the door, I flipped back a page, to see the same scene from the game part of the dream, with the door still closed and locked, so I tried flipping over one more page again, to see if I missed anything, then back to the table of contents, and all I can really say about that was some of the words were blue, as if they were hyperlinks.
We're going grocery shopping as soon as Mom gets back though, so I suppose I should go get ready :3
