Dreams can be viewed in color, black and white, a mix of both, or neither as the brain deciphers the screened images consciousness is observing while focused in other grids. As our perceptions of reality, including television and computer monitors, has upgraded in terms of quality and color content - so too have our dreams. It would appear that what you view and process in physical reality shapes your dreamscapes.

Back in the day when TV was black-and-white - people reported black-and-white dreams. As we moved to color TV people remember their dreams in color - the brain adapting to grid content.

Computer monitors and other virtual reality experiences have led to more clarity and vividness in dreams along with an increase in lucid dreaming for many people. It's all about programmed interpretations of the endless screened images one experiences at different levels of conscious awareness in different space-times (grid realities).
