Hello research, and welcome to the forum.
That saying is a very old method of programming, dates back to the eons! In the logic world it tells us of the times where bed bugs would wake children in the night, England, Scotland and countries like this where infested with these little critters.
But in the world of programming, this saying is intended to make children fear sleep, so when they are actually going to sleep they have the fear of bugs crawling and biting them, and the relaxation state is hard to reach, many children are programmed through their dreams, and if they go into sleep state already freighted it makes the programming a whole lot easier.
Children are targeted through many sayings, like the boogie man will get you! Santa will not reward you! Or the Easter bunny and all these fabricated characters, parents use these to bribe their children but at the same time programming them to believe that a ââ¬Ëfable personââ¬â¢ will magically bring them gifts if they do as they are told..
