About 100 years ago, Freud declared that dreams are the path to the unconscious. Oddly enough, despite all the progress in science today, we are no closer to understanding why we dream. Does dreaming have a biological function or is it just noise? Dreams can be in color or black and white, with or without sound, and yet we still don't know why it happens at all. So I put it to you - what do you think is happening when we dream?
