Paranormal activity refers to events or phenomena that cannot be explained by current scientific understanding. This includes experiences such as ghost sightings, unexplained noises, and other occurrences that seem to defy the laws of nature. People often report feeling a presence or witnessing objects moving without any apparent cause. Many cultures have their own beliefs and stories about the paranormal, often involving ghosts, spirits, or supernatural beings. Investigators in this field, known as paranormal researchers, use various tools and methods to study these phenomena, hoping to find evidence that supports or debunks claims of the paranormal.
