A year or so ago I gave my sister a book by Lillian Braun. It was a mystery with the main character a cat with 'special' powers to solve murders. Very light interesting read. My sister left it in her car as she noticed on the dust cover about the cat with physic powers. She was afraid to take it into the house. A couple days later she was driving her very old car down the street and the radio came on full blast & scared her. It happened again a day or so later. By then she had figured out it was the book that was demonized so she threw it out the window while she was driving down the street.
Demons also made her computer crash. I sent her an email with a list of quotations from the old WT publications. Her computer crashed as she opened that email and for some reason she thought it was demonized. I don't think she realized the quotes were from WT stuff. (Personally I believe that's where her demons are coming from - all that WT stuff.)
