The visual journey of memory, of memories, is possible in certain situations of hypnosis or dream. The work on this film is focused on the ability of immersive films to provide the sensation of dreamed images. How to visualize what is in the past or in the future, in short what is absent from the present. This film is a journey, a mental itinerary that uses all the scales of the human gaze to image the memory, from the infinitely large to the smallest invisible.
