Well I'm sorry, but I have pondered this clue all day and still have no idea as to how to get the quest! No need to tell me here and spoil it for others, but some of us just don't get it lol
I thought I had missed something with this quest, because I hadn't flipped a switch, but after discussing it with a friend, I realized that I hadn't. I appreciate the idea of seeing a glitch's dream, but, to be honest, this felt like a waste of time. :/
I got the reference! It just seemed like choosing "down" here would lead to...more. But hey, I've had naps quite like this in line at the DMV, so I get where they're going with it. 's cool.
