Have you ever heard someone say, "Keep a knife or scissors under your pillow, it will keep bad dreams away"? It might sound strange, but this is an old belief that has been passed down in many families. In some Indian households, grandparents have suggested keeping a knife or scissors under a child's pillow, especially when the child is having nightmares or waking up scared at night. And interestingly, India is not the only place where people believe this. Similar traditions can be found in different parts of the world. But why a knife? Why scissors? And how did people start believing that these objects could protect someone while they sleep?
