The accounts of encounters with Black Eyed Kids vary with their observable details, except for two main factors: their dead, black eyes which you see and can never forget and the feeling of utter horror and doom which you will continue to feel every time you think about them. If the eyes truly are "windows to the soul" then these entities have no soul, or that soul resides in hell. Remember that the next time you hear a knock and think it's just a harmless kid or two, and all they want is some Halloween candy, or to use your phone, or a ride, or to come in and warm up, because what they will take is something you literally can't live without.
