To me, those pictures actually reminds me a plce in Finland, called Näsinneula Tower. The interrior is very similiar. And makes it special, is that the tower consist of a exterrion "ring" that keeps spinning in slow pace.

Unfortunately, internet fails to find any pictures from the interriors. But I'm lucky enough I should be able to find some photos from my own album (and perhaps some of the interrior from my memories).

ah, but this is on the ground

But the architecture still very similiar. And the place I mentioned could be on ground (making is sort of carousel). And I do actually belive there's one on ground too somewhere around the world. =3

Sometimes when my dreams are lucid enough, I see massive, seemingly endless complexes. One dream had me in some very arid, dry place. The sun was intense like I was in a desert. As far as the eye could see, miles of clean, white concrete slabs. And on the edge of the plane, there were staggering sprawls of large, concrete structures, both ranging from spheres to a myriad of angles and arcs. As for the function of these places in my dream, it's beyond me. Damn, I wish I could completely remember the basis of these structures so I could illustrate what I see. Most of the dreams end however with a blurry transition into another environment and before I can remember what I saw, most of it is as you said "evaporated" away from my memory.

Non-euclidean spaces, strange and scary architectures seen in vivid dreams... Have you read any forbidden books lately? It's probably a way to remind you to bring back your copy of the Necronomicon to your local library.

More seriously, how do you manage to remember anything of your dreams? Do you draw the pictures immediately when you wake up, or do you try to remember what was inside to work on them some time later?
I'm having a hard time remembering even the slightest of the plot, let alone any kind of detail; it can get frustrating at times... And for some reason, I wonder, was the sandwich on the table of particular significance to you?

no, the sandwich was of no special significance other than eating it made me thirsty and some asian dude showed me to the vending machine afterwards where I saw a 2 liter of grape soda inside for 89 cents. It seemed surprising because soda just isn't that cheap anymore (except maybe faygo !) I didn't have a cup to pour it in and share with other people, so I was kinda saddened by this small thing despite an otherwise perfect world. Off to the right of the machine was a "grab and go" angled wire rack which was full of snacks and more drinks, but I didn't draw that.

Most of the time, I draw these things right as I awaken so they don't go away. Being awakened abruptly or given things to do soon after waking up normally erases a person's dreams immediately; I believe this is a natural human reaction which is why if you want to have and remember dreams you need a good night's sleep and not be under a tight schedule. However, that's really only if you want to remember. Often times, people in stressful situations have a lot of nightmares because it's the body's way of preparing you for challenges ahead (usually requiring your creative, problem-solving skills, which is why they are put to the test allegorically in "nightmares")

Interesting.
My dreams are constantly changing. Flux dreams. The plot changes, the surroundings.. time of day. etc.

But what I find interesting is that if I sit and think about it long enough, I can recall what happened in a dream, how something looked, or even the color of the setting.
Idunno, I think it's because of my photographic 3D memory bit with the way my brain works.

BRAAAINS

When I usually have dreams they make no sense usually xD Or its crowded with so much imagery in surrounding. Aside from my semi-rare old hag nightmare x____x;
