Kids! The unknown scares us. This scares us. That is why they are afraid. This fear makes us feel the ghost of fear. Ghosts are our delusion. Sometimes we are afraid of our shadow. She becomes a ghost for us. Then the question arises that there are ghosts? No answer to this. We tried to explain this in the ghost of crow-crow. Things we don't see. If we are afraid of her, she becomes a ghost for us.
