Poltergeist Parallels and Contagion

Poltergeist Parallels and Contagion examines recurring similarities between reported poltergeist cases and develops the idea of paranormal contagion. Darren W. Ritson considers accounts in which investigators, relatives or other people connected with an active case later reported disturbances in their own homes, away from the original location.

The book expands on the earlier Contagion: In the Shadow of the South Shields Poltergeist, adding a substantial chapter on historical cases from Britain and overseas. These accounts are used to compare patterns of activity and consider whether apparent connections between cases point towards a shared process, rather than isolated incidents. The discussion remains centred on claims, case records and hypotheses within psychical research.
