To this day it is not possible for any branch of science to visualize dreams, memories or the subconscious. PsychologY, medicine and engineering are clearly restricted when exploring thoughts, memories and dreams.
No matter how advanced research may be, the possibility to create realistic images of thoughts and dreams still lies in far distance.
Should it ever be possible to reproduce human thought, it will be the beginning of a new era. BARELY imaginable are the resulting chances and threats for mankind.
Art in all its disciplines has always pleaded its right to visualize the fictional and the unconceivable. Needless to say that the results of artistic efforts to depict myths, dreams and religious conceptions vary widely.
To begin with, those depictions are always shaped by their period and its scientific knowledge and religious notions.
The artist's subjective perception, his political surroundings and focus influence the outcome of his product significantly.
Our period, the era of digital evolution, renders possible the realistic visualization of any given fictional idea. Delusion is ubiquitous.
The distinction between reality and fiction has become impossible when consuming new media.
