Öz This paper intends to deal with and discuss the relationship between out of body experiences, near-death experiences, lucid dreams and theory of parallel universes, which is the popular version of quantum mechanics. Without disregarding the affinity in the fields of para-psychologic phenomena and science, it analyzes the degree of this affinity in these fields as well as the problems which seem to arise in the relation between para-psychologic phenomena and science. In the final analysis, it aims at establishing a synthesis according to logical results out of relations between the claims made by the theory of parallel universes and para-psychologic phenomena.
