Also before I go to sleep I'd like to just post one dream I had a year ago that was one of my most vivid and had several of these examples within it, and shows how these difficult to describe things occur in my dreams.
This is also one of the few more coherently written dreams I had written down:
-Super long and realistic Stalker dream with a mix of Metro 2033, was inside game but felt like real life, all the mutants were there too, super spooky. Turned from exploring soem abandoned city to fuarrrking Cyberdemon huge monster out of nowhere crashing through the walls and I had a BFG9000 that I picked up a while back and fired at the demon, killing it instantly turning it into a charred mess, and I picked through him for loot, and found none, then I went to a nearby train station which was still operating and waited for train, decided to skip time somehow and I did but now it was night, I hear a disembodied voice, like a helper over an intercom tell me that I can skip forward in time to try to avoid baddies but if you do it too much you are left to fend for food and resources on your own instead of a ressuply, now its fuarrrking night and I missed the train, and theres a snorkeler and I'm scared shitless because I have no weapon, or no ammo for my weapon, only flashlight. Its not attacking me yet but just on the far side of the station platform, suddenlly train arrives, no people in it, still has lights, I realize its driven by a script and I'm still totally alone here, but I get up and it starts away, feels really good to stand on moving train, not actually falling off like most games but secure and able to move around, as it drives I see a whole railyard and station complex outdoors just full of trains, all with lights on, all going through scripted motions with no passengers or conductors and I wonder for a sec how this can all still operate in a post apocalyptic city kek. Still realize its a game I'm in so thats how, but didn't realize I was in dream. The train now takes a wide turn and I'm hoping its going to lead me out of the city but its going awfully close to the inner portion, behind me is a neverending stretch of apartments and commie blocs all squeezed together, have to watch out for random metal soykaf and poles and overhangs because they stretch out over the tracks but as I come up to them I easily clip through them all and stop trying to avoid them, then on the other side the graphics seemed to have improved tenfold, everything is crisp and clear and super detailed, from lighting to props, I can see all sorts of enemies including snorkelers startled by train and wanting to kill me, and I still hsve no ammo in my weapon, the only lighting is from train and random fires, illuminating all these spooky enemies, but train is going to fast for them to do anythjng, suddeny i get a dejavu inside a dream and remember that this level im in now was part of the demo I remember playing for it and I dread knowing whats coming up next, still no ammo, and the train starts to slow down... still in the middle of this shitty city, and I have that voice over intercom aagain telling me to get ready and going over tips, to survive, the train slows down and just ahead I can see the track is gone, just a few planks of wood ending in the dirt of the street,covered by snow now its stopped and qa these enemies start crawling around snorkerlers and some nasty mutants with giant carnivorous stomachs and I say fuarrrk this and take off my breathing mask, and my gear like a coward and close my eyes and jump into them... feeling them grab and strike at me but nothing painful as sensations are lessened and then dream ends.
