Apparently if I ever have some sort of condition sleep-related, or am just plain sick, my game memories take over (based on latest, or heaviest impact-games) and that's how the inside of my mind will show up when I'm fixing the issue. Fortunately, it's only especially relevant when I actually do sleep.
Last time I was really sick (kudos to a black mold infection; already fixed), I also got really far into S.T.A.L.K.E.R., and got into the really interesting missions where things started to get weird. I also ran into numerous bloodsuckers and controllers and etc.. Let's just say, my mind and the ruins of my body while I was out cold for a few days ended up pitting me in a STALKER rendition of how my body has become (my head being the final portion of the game, of course). It got pretty interesting, since as I was racking up more kills in that pocket reality, I was getting better IRL. But of course, this is still essentially STALKER I was playing inside my mind, and I fortunately had the quicksave button in my head; plus, the difficulty wasn't that much different.
Just similarly, I've been pointed out that I've been lacking sleep, or at least looking like it by my perspective (my sleep schedules haven't really changed, but other observations have got me second-guessing and worrying about it, which makes it even worse, because NOW I must SHOW progress of getting better, instead of letting nature take it's course. Maybe I ate bad food, or not enough. Let me worry about it and take my course of action which has been reliable, though time consuming.). Kinda a side effect of not having much money, and having to switch priorities from eating to paying the bills (or at least resorting to rationing). But after playing quite a bit of Fallout3, my mindscape changed scenery to the Fallout universe. 50s-style tech and everything. What sucks about some of these dreams is that I can't wake up unless certain conditions are met or something, or I figure out how to access the console, and execute a "wake up" command or exit the game.
In any of those kinds of the dreamscape, the first thing I do once I go lucid is find a way to cheat, or bring up a console, or have my soul hack into my brain (or brain hack into body), and find a way out (through a bit of hacking), so I can exit by will when the time comes. It's really frustrating when you usually sleep for 7 hours or so, that a dream keeps you asleep for up to 11+ hours because it doesn't want to let you out unless you tie up a loose end, and not give you hints on how to fix it or what the loose end was in the first place. I'd like to sleep-in by will, not because a dream world decides to be an asshole.
