Mostly I do not remember any dream when I wake up. But if I do, it are always complete stories. Like a proper book, so with a realistic plot. In some dreams I play a role in it, but in others I watch. The stories are completely different, but without exception with the same line: things are taking place, can not be influenced, are unstoppable. It sounds not positive, but I never had bad feelings about it. Actually I do like the stories. As Hawtsean mentioned, it could be an exhaust valve for my brain, a way to accept life as it is.
I dream in pictures, motion pictures, but never see actually faces; more characters. And I am not sure if I see colors, as if your brain does not need colors to be influenced in a dream. It is the brain himself who creates the emotion.
