When I was five, I used to believe that on some nights a wicked witch would come upto my house and peck on my window outside my bedroom with her index finger, but never enter the house fortunately. I got that idea from some picture story books that were read to me, where a child that was in bed on a windy night thought that a wicked witch was tapping on his window, but as it turned out, it was just the branches of a tree hitting the window. I did not understand the second part of that story and I still believed that there were witches around even though my my tried to explain it. Fortunately, I got over the fear of witches within two years.
