Lite Bright, a toy from the 70s (the issue started with the silly jingle in the commercial and then grew into fear of the toy itself);
A very tall Orthodox Jewish business associate of my father's. Whenever he'd come over, he'd ask to hold me, and then he'd lift me up above his own head, and I'd panic. I started hiding in my closet whenever I thought he'd come around. I think his name was Liebisch? The black clothes and his black facial hair scared me silly, which is weird, because my father had black hair, too. Maybe it was the hat?
Dogs and nature abhor a vacuum.
