The She-Creature (1956)

Using hypnosis, Dr. Carlo Lombardi claims that he can have his patients regress and recover memories from their past lives, thereby proving that reincarnation exists. He also claims that the spirit of these past lives can be brought forth to take physical form.. A series of violent murders by a creature that seems to disappear into the sea suggests that Lombardi's claim may be correct. The medical and scientific community believe him to be a complete fraud but one enterprising businessman sees the opportunity to make a small fortune with Lombardi's ability.
