This paper examines the quantum cosmological framework of Dr. Yukikazu Matsushita, proposing three revolutionary principles: (1) Time flows from the future toward the present, meaning conscious intention projected into the future "returns" as present reality; (2) Parallel worlds exist as a field of possibilities that converge at the end of physical life; and (3) Past-life experiences and déjà vu are resonances with "field memory" encoded in specific locations. By integrating these with retrocausality and many-worlds interpretation, this study provides a scientific foundation for how intention creates physical reality. It serves as the ultimate theoretical anchor for the 'Inside-Out Universe' series, offering a path to liberate humanity from the fear of death and the unknown.
