I think the idea is that we should have some sort of thread in which we make fake news, with the articles being related to the dreams we've had?
Okay, so a Dreamscape log/newspaper. However, in case you tend to get recurring ones, be sure to tell the worlds apart if they each have their own canon, and take into account the timelines of them too. I mean, I've had some worlds operate on a 48-hour system and such; or simply, really long days. Others operated on 8-hour cycles or less (4 hours of light, 4 hours of night).
Having already awoken from passing out after fatigue getting the best of me (actual sleep part over, now I want to dream once I sleep again); I'm just posting for the time being. Could LD afterwards from this (since I'm still zoning out a bit). Always a good gateway system is keeping your room as-is, like the starting/ending point. Examples include: Cloudbuilt, and the hospital room the main character is recovering in, and Tron Legacy, and how Flynn's club is the same when transitioning between worlds from his computer in his office to his office in The Grid (no change, except being digitized now, and upon leaving, his arcade/club is still the same, even externally; only truly out of place place on the Grid, based on the local scenery when the movie really begins). Speaking of which, carry devices that can digi-struct (Tron/Borderlands) when you need them, out of convenience. I mean, I always carry a few weapons, a method of air travel, and maybe a light cycle on me to get to places on the fly.
Just run, jump, and ride.
What gets trippy is when your room remains the same, until you no longer observe it, and it either adopts the surroundings as a new theme, or the room completely disappears around you as you aren't paying attention to it. I've had some non-euclidean stuff go on like that before. Blinking or closing your eyes for a moment makes a better shortcut.
EDIT:
Just remembered one world I visited; apparently I was a Heavy Machine Operator on an off-world mining rig on some ruddy barren old rock; though it wasn't Mars. Mars was already colonized at that time, and is a fully lush blue sphere like Earth. The crew I had reminded me of my pirate crew in another one where my drawings are part of the same universe, and apparently the crew was not all that different. Funny enough, my equipment that had the most usefulness/power and etc. just happened to share the same name as my flagship in the other dream. Shared information across universes, mayhaps? I can maybe share info across an 'out-of-place device'. I'll try to carry a psychic console with me to interface with for my logging and such. Anything with no mass to it is easy to carry. I'll just make sure it uses a shared server linked to my conscious mind.
So, instead of dreaming right now, I'm getting memories of other dreams recovered. Even minute details are being recalled a bit. The coffee over there could use some work. Didn't wake me up there nearly as well as the Blue Tokyo Eiffel Tower made of Crap (as in lost valuables and other artistic nonsense which also happened to turn into a marketplace beneath) provided, and didn't taste nearly as good. Now the French?/Japanese?/Frappinese? over in the other dream, they know how to brew.
EDIT EDIT:
Only other thing I haven't tried yet was like in What Dreams May Come, and having my entire environment be paint-based.
