Tucker Carlson, Trump supporter and former Fox News host, claims that ca. 18 months ago he was attacked by a demon in his bed. He even had physical markings in form of scratch marks and wounds after the alleged attack which are supposed to be evidence that it really happened and not only was something that took place in his head and his imagination. That's interesting, but more as a tell-tale sign about Tucker's personality than as a proof that there are demons out there. To me it's more likely that Tucker Carlson had a special, wild wet dream than a demonic visit, but then I am a skeptic when it comes to demons although they are part of our history and ideological heritage.
The Church, always ready to subdue people by scaring them, has up through history preached over "demons" out to catch our soul and drag us down into Hell. They had carvings of demon gargoyle figures on the churches and kept warning people against associating with these hellish creatures. Also there were lists of demons, names and hierarchy, that turned it into something more tangible: "This is not figments of the imagination, no it's real, and they are out to get YOU!"
