"Poltergeist" comes from the German words poltern, "to knock" and "rumbling spirit". The history of poltergeists can be traced as far back as ancient Roman times. Reports of poltergeist disturbances cite loud noises, lights, smells, physical and sexual assault, telephones ringing, and in general create unexplained disturbances. Some people believe that poltergeist activity is caused by an unconscious form of telekinesis. Poltergeist activity usually takes place when a particular individual is present - usually young teenagers at puberty who has emotional problems. A poltergeist is often thought of as a negative spirit attracted to these teenagers.

If you love what you are doing, you will be successful."
