No, You Don’t Have A Ghost In Your Room
You know that “chill” in the air that makes you feel as if someone or something is there, lurking in the dark? It’s referred to as a “feeling of presence” (FoP), and it has nothing to do with paranormal encounters but it has everything to do with your brain.
By studying several patients with neurological disorders, scientists from Switzerland found that the eerie sensation is not a result of demonic paranormal activity, but rather a misattribution of sensorimotor signals. Due to damage in some specific parts of the brain, your own neural activity is mistaken as an otherworldly presence.
Actually, you are the ghost. Furthermore, lead researcher Dr. Giulio Rognini and his team built a machine that creates similar sensory errors when test subjects poke it, which causes them to become overwhelmed with vibes as it returns the favor. The important aspect of the study, though, is that Rognini believes the technology can be used to help restore schizophrenic patients to a healthy mental balance.
