What kind of evidence do ghost leave behind?

Evidence of ghosts often includes unexplained phenomena such as cold spots, flickering lights, and strange noises like footsteps or whispers. Some also report visual manifestations, like orbs or shadowy figures captured in photographs. Additionally, electronic voice phenomena (EVPs) are recordings of voices or sounds that are not audible at the time of recording. Physical evidence may include objects being moved or disturbed without an apparent cause.
