As we know it, surrealists had a very particular way to compose their art : most of them used what is called "automatism of thinking", because they thought that the subconscious was able to make great things by itslef, without the help of the consciousness. Miro (a Spanish painter) used to say something like this : "When I am seeking for inspiration, I come to my little house, and close all the windows. Then I wait until it is night and I lie on my bed. I look my ceilling and then, as I'm falling asleep, I see these beautiful things in the darkness." Furthermore, we all know (thanks to our own experience), that dreams are often strange, in the same way that surrealistic works are strange. This is why I choosed to make an image about dreams. I read a few things about dreams, but the most interesting was the book written by Freud about interpretation of dreams. It really inspired me for my image, so I will tell you a few things about Freud's work (I'm not an native English speaker, and neither a psychanalist, so I may make big mistakes about the words I'll use in this text. I apologize for any eventual error) : The dream is the keeper of the sleep. People always have things to do, or desires to accomplish. If there were nothing against that, people would not sleep, because they would (unconsciously) think it is a waste of time to sleep. But as sleep is vital, we have a way to keep the human beeing asleep : it is the dream. Freud thinks that the subconscious shows you and makes you live your desires, so you don't have the idea to wake up. It is the base of his theory. The subconscious will, to keep you asleep, simulate your greatest (or nor so great) desires and wishes, until you have enough slept. But, there is a little hurdle : the subconscious also has the role to keep secret your deepest thought for your own comfort. It erases bad memories, for example, so you can live better. Said otherwise, it tries to prevent that these toughts go from subconscious to consciousness (what you can really remember, what you think, what you know about you and what surrounds you, etc.). So, to keep you asleep while not reavealing too much of the secret thoughts, the subconscious must compose, "make" a dream, to transform the basic thoughts the "ideas" of the dream, into the coded scene you actually live. The ideas always contain at least one thing you encountered the day before you sleep (it is called the trigger idea). To create the coded dream, it uses four mechanisms : - "staging" : each "idea" of the dream has to be represented by something in your dream. This representation can be a bit altered, or not, or very altered. Quite often, the ideas are represented by symbolic objects (like in surrealism sometimes). So your house can appear as your neighbour's one, but you'll know it is yours. If there is a dog in your dream, it can be there to represent any animal, etc. - "condensation" : several ideas can be represented into only one element in the dream. So a dancing elephant with your sister's head can represent three ideas : dance, animal (elephant), family member (mother). That is why there are often more ideas than elements in the actual dream. - "shifting" : to scramble even more the main idea of the dream (the one that will make you sleep), the subconscious changes the importance of each element. The most important idea will be just a detail in the dream, while a lot of other ideas will get more evident. - "reworking" : once each original idea has found a representation in the dream, the whole thing is mixed again, so the elements get a order deprived of meaning. Freud, knowing all these mechanisms (after studying his onw dreams), explains that it is quite easy to disassemble the dream to get back to the original thought. He warns the reader anyway : it can be dangerous to know what we really think, because it could cause troubles like nervous breakdown. All the elements of my image have a relation with dreams, as I will explain it in the next section. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The central element of the image is a brain, because the brain is the part of the body where conscience, subconscience and so on, dreams are all from. You'll notice this is where the light come from. The brain is a mesh I found on the web (sorry I cannot remember where). Under the brain there is a kind of tower. It is a car park. Don't ask why, I once saw this thing in a dream and it was a car park. So I put is there because I thought it could make a nice central element. I chose neat reflective surfaces because in dreams, there are often not natural things. This corresponds well to surrealism. The whole object is just CSG with a macro to make the surrounding steps. Around this central tower, I put a ring of strange shaped flying water. This is a symbolic representation of an enclosure, a fence like a customs at a frontier. It is there to show the separation of concsious and subconscious. The object is a blob which spheres are placed randomly around the tower. You can notice that the ring is half transparent, which means that some ideas can pass, while other cannot. Flying over the ring, there are four bubbles clusters, made in the same material than the ring. They represent each one one of the four mechanism of the creation of a dream. They are over the frontier ring, because they are the ones that make the "ideas" allowed to pass or not. They are also blobs. At the background, on the right side, there is a library. This library shows the incredible amount of information that a human brain can contain. Furthermore, it can be understood as the memory from which are taken all the ideas of a dream. The library was made with the Library macro (slightly modified so there is no titles on the books), written by the wonderful Gilles Tran. At the left background, there is a bed. The bed is typicaly the place where you sleep, and so, where you dream. The structure is modelised with sphere splines and CSG. The mattress is a superquadric ellipsoid, with a texture that make the wavy sheets effect. The element on the left foreground is a totaly surreal shape which represents Freud, as a strange object can be someone in a dream. The surface is reflective, because Freud used to reflect a lot ! (Honnestly, puns can happen in dreams.) This is a sphere sweep. On the right, this strange thing is the combination of an eye and a flower ("condensation" mechanism). As for the tower, the shapes and textures are really stylised, in a surrealistic fashion. The eye is a surface of revolution, and the other parts are CSG. The whole scene is included in a high landscape covered by weird bubbles. The hills are a height field, and these bubbles have been created with the MakeSnow macro, again by the magical Gilles Tran. Notice the disproportion between all the sizes of the elements. It is common in dreams to have objects suddenly bigger or tiny. All the light colored splotches on the hills represent the ideas of a dream : hard to distinguish, a bit sallow and not substantial. They are made with simple light sources spread over the heightfield with a macro adapted from the one written by Marc Jacquier for his on-line POV-Ray tutorial. Finnaly, it is a night scene, as the sky is dark, as dreams often happen in darkness and night.
