The Periodic Table of Paranormal Elements
Commonly known as an EVP, this is a sound or vocalization which is recorded with an electronic device such as a digital voice recorder, which was not vocalized by any human present during the time of the recording. This is believed to be the voice of a spirit or deceased human which is recorded. As opposed to a disembodied voice, an EVP is not audible to humans.
Intelligent interaction, between a spiritual entity and a human being, using the features of an electronic device or a software application running on an electronic device. As opposed to an equipment anomaly, this element involves active participation on the part of the living person.
Ectoplasm is defined as a white, misty, liquid substance that oozes from the orifices of a medium during a seance and can be formed by spirits into a humanoid apparition. The subject of many hoaxes, it has been substantiated, photographed and described in detail by Benjamin Alexander, a former spiritualist, who was terrified by his experiences and later became a Christian evangelist. Ectoplasm is said to be light sensitive and vanishes in the presence of light.
An equipment anomaly involves a piece of equipment which behaves in a way which is not consistent with the designed function(s) of the device which is not considered to be possible.
