Carbon Monoxide and Apparitions

Could an invisible environmental hazard explain some experiences reported in haunted places? Carbon Monoxide and Apparitions examines the chemistry of carbon monoxide, how it injures the brain and heart, the range of symptoms from headache and confusion to severe neurological effects, and the limits of linking poisoning to visions or sensed presences. Historical cases, building systems, alarms, exposure investigation and emergency response are discussed alongside the dangers of retrospective diagnosis. The book carefully distinguishes documented poisoning from mere possibility and makes clear that paranormal investigators and phone apps cannot replace certified detectors, clinicians or emergency services. It is a practical, evidence-based bridge between environmental health and anomalous experience.
