If you all are wondering why I got scared of doorknobs and traffic lights when I was a kid, here you go.
TRAFFIC LIGHTS: I was in my father's honda, I looked behind me, and my mother was walking away from the car. I turned around and there was a floating traffic light that made a loud train and a bloodcurdling scream sound at the same time. I woke up in tears at the horror of the sounds.
DOORKNOBS: I was in my garage, and there tons of doorknobs all over the walls of the garage. I burped, and then the doorknobs came alive, floated out of their place, and as they followed me, they opened what it appeared to be mouths, and the mouths had vicious teeth in them. As they went after me, they all made a roar that sounded like a lion. I stared at my ceiling for a while in awe, from the distorted nightmare.
EDIT: Note that these are childhood nightmares.
