John recently picked up your five-year-old daughter from kindergarten. The rest of the evening went well, but with the onset of darkness, the girl became too anxious. Before going to bed, she asked your husband to look under the bed, check all the closets before turning off the lights.

Half an hour later, the girl starts crying and calling for your help. "Mom! Dad! There's a babadook in the closet!" She buries herself in the blanket, and you turn on the light. John opens the closet, but it's empty. You sit down on the edge of your daughter's bed and tenderly wonder where she came up with such a character. "A boy in kindergarten told me today that this monster hides in the closet and eats children!" The girl whimpered.
