The work tells the birth of a shared imaginary space. It opens the virtual space to the bodies of the spectators by mixing the capture of a volumetric camera and mapping. This chapter is part of the work Heterotopia which explores the spaces connecting us to our utopias. Here we embody a dreamer lying on his bed. Projected on the ceiling, a giant screen becomes the mirror of a nocturnal imagination where we see our own body floating in space. Floating in a sky of memory, our body travels through pieces of spaces and objects belonging to the memories of Neon Minuit. The subject is no longer the object seen on the screen but the relationship we have with it. The memories are treated aesthetically as a cloud of points. Cut out, sculpted, colored, the cloud becomes a fantastic decor linked to our reality. The colors evoke a day lit by a rainbow, an afternoon where the sun becomes the multicolored neon of a megalopolis. This technique allows to visually reformulate the motif of an unconscious, an intangible matter.
