Psychics seem to have powers that go beyond what we mere mortals can even comprehend. They can apparently see into the vastness of the universe and make sense of everything, or so they want us to think. With 1 in 5 people in the US having visited a medium, it’s safe to say that many people do believe in psychics.
Even if mediums claim to be telling the truth, they can concoct a story just for fun and nobody would be the wiser. This happened to one guy who was a victim of a psychic’s false claim and it ruined his marriage.
