In the movie, Demi Moore and Patrick Swayze play a happy couple who are deeply in love. After Sam (Swayze) is murdered, he finds himself trapped as a ghost, and in order to warn his wife Molly about the dangers that face her, he communicates through Oda Mae Brown (Whoopi Goldberg), using Mediumistic Communication. Oda Mae is the only one who can hear Sam, and in knowledge of this she helps him by using herself as a means of communication between Sam and Molly. Unlike EVP, Mediumistic Communication does not require an audio recorder. The similarity, however, is that in order for the ghost's voice to be heard, it needs to first transfer through the proper form - in this case a psychic.
These movies clearly express the theories of EVP and Mediumistic Communication, through a means that allows people to truly understand what these two forms of phenomenon are all about. Using a type of media that allows factual information on these topics to be prominently discussed while still keeping the storyline fun and interesting, these two movies show an excellent example of how to explain such phenomena in an intelligent way.
