New mobile applications revealed through my dreams

An excerpt from one of my dreams: "virtual map shown colors emanating from various places nearby, showing what emotions people were giving off, with cool colors indicating negative emotions and warm colors indicating positive emotions.

You can then learn to avoid, or instead benefit from specific world regions”
