Future Life Progression is what you get when you explore the strongest, positive elements in the subconscious. Freed from logic, reason, and convention these elements will build their own picture of who you can be which, by extension, is partly who you already are. The aim is to create a transcendent experience that "unreasonably" amplifies itself in the present.
In spite of what you might think this is not a fantasy, but an exercise in self-reflection. People need to be well grounded in order to integrate these experiences.
