Explanation:
Parapsychology is the study of paranormal and psychic phenomena, including ghosts. This scientific field aims to investigate mysterious incidents that do not have a clear explanation through conventional science, such as apparitions, ESP (extrasensory perception), and other supernatural occurrences. Researchers in parapsychology strive to apply rigorous scientific methods to explore these phenomena, seeking to understand whether they can be quantified, explained, or reliably reproduced under controlled conditions.
