According to a 2005 Gallup poll, 37 percent of Americans believe in haunted houses, and according to a 2013 HuffPost/YouGov poll, 45 percent believe in ghosts. These are surprising numbers, but the next time you hear a spooky sound, don’t call the Ghostbusters—get a scientist instead. Behind every shadow, poltergeist, and disembodied voice, there’s a perfectly rational explanation.
10. Electric Stimulation Of The Brain
Frightened witnesses all over the world have seen the shadow people. These dark beings are glimpsed out of the corner of the eye only to vanish when confronted. Many believe them to be demons, some think they’re astral bodies, and some say they’re time travelers, here for a second and gone. However, some researchers have a more shocking theory.
When Swiss scientists electrically stimulated an epileptic patient’s brain, things got really spooky. The patient reported a shadow person sitting behind her, copying her every move. When she sat up, it also sat up. When she bent forward and grabbed her knees, it reached around her body and held her. The doctors then told her to read a card, but the shadow person tried to take it out of her hand.
What happened was the scientists had stimulated the left temporoparietal junction, the part of the brain that defines the idea of self. By interfering with the area that helps us tell the difference between ourselves and others, the doctors screwed up the brain’s ability to understand its own body, thus leading to the creation of a copycat shadow person. Researchers are hoping this is the key to understanding why so many people, both schizophrenic and healthy, encounter shadow beings and other creatures like aliens.
