"Ghost phenomena" refers to experiences or sightings that people attribute to the presence of spirits or supernatural entities. These occurrences can include visual apparitions, unexplained noises, or feelings of being watched. Many cultures have their own interpretations of ghosts, often linking them to the souls of deceased individuals who have not moved on. Research into ghost phenomena often involves paranormal investigations, where teams use tools like EMF meters and infrared cameras to capture evidence. Skeptics argue that many ghost sightings can be explained by psychological factors, environmental conditions, or misinterpretations of natural events.
