Stephen Hupp, a clinical psychologist and professor at Southern Illinois University (USA), explained that one theory is that people may see ghosts because of the human brain’s tendency to find patterns, especially human figures and faces in dimly lit rooms or in unreadable photographs. He told the news about it portal Live Science.
“This is pareidolia. “A great example of this phenomenon is when someone sees faces or animals in clouds, and another is when random shapes and shadows in a dark house look like ghosts,” explained the expert.
Therefore, almost all cases of people seeing ghosts involve obstacles to correct judgment; poor lighting, emotional arousal, lack of understanding of how recording devices work, and pre-existing beliefs and personality traits. All of these could be reasons why people see ghosts.
He also stated that belief in paranormal events also brings comfort, allowing people to think that their deceased loved ones are nearby and caring for them.
