This is an idea based on childhood stories, when any gaps in knowledge were filled with imaginary and often dangerous mythical creatures. Some of the things above were real or based on reality, others were imagined and were kept alive by other children talking about them as if they were real. I didn't know what glue sniffers were, but they sounded bad, so I imagined they were some kind of demonic creatures. And no one actually saw the witch because she was often on holiday. The world seemed so dangerous in those days, but it was also exciting and new, without the weary cynicism of adulthood.
