Dream Therapy 3 takes place some time after the events of the first two chapters, but is meant as a standalone sequel to the series. In this game, you will assume the point of view of a psychiatry intern working at the Mental Health Division of Drake Pharma.
There, a revolutionary technology is being developed, which allows for the transfer of unconscious minds as a way to improve behavioral therapy. However, things rapidly degenerate when your supervisor, Dr. Kumiko Tamura, goes missing. You find yourself forced to enter the Dream World as you are plunged into a web of intrigues blending reality and fiction.
