When I was a kid, my mom's friends used to tell me that there was a monster in the basement and I was to never ever go down there. I visualized this huge, purple, muppet-type creature covered in fur with yellow fangs and ginormous claws. I was never afraid of anything ever as a child, but I was absolutely petrified to go into that basement. I must have been about 5 and I still remember how real that belief was! Now I'm pretty sure that the grown-ups were smoking weed down there!
