At first the pyschologist doesn't see the changes so long as actually live them as everyone else does. Once he recognizes what is happening, he attempts to make use and take control over George's dreaming in order to make a better world - so he claims. There are quirks that go along with George's dreaming, subconscious oddities that may not make full sense of the suggestions of his dreams. One example is of a suggestion to solve overcrowding in the streets. Another is when a suggestion to end all wars between man on Earth results not in total peace, but an invasion, of a now-appeared moon colony, by aliens from deep space.
Nothing ever happens exactly as hoped for.
That had happened four years previous to the current episodes in the film. Along the way arrive peaceful aliens who are best described as odd sea-turtles in appearance. Their thoughts and logic are very Taoistic and offer one to suggest an answer to one's self rather than asking it of others. This comes down to the belief that all goodness and all answers lie within ourselves. There is no flash and flutter.
