Weird things used to freak me out when I was a kid (3-4-5 years old). Some things made sense. I had nightmares for years over the Frankenstein Monster after seeing Abbott & Costello Meet Frankenstein on TV one Saturday morning (yeah, the least scary of all the horror films).
But the things that freaked me out the most were commercials.
First, there was one featuring "The Scorcher". In Saskatchewan during the early 70s they had a mascot for their anti-forest fire campaign (I guess they couldn't afford Smokey's fee) and it was this grinning, blood-red devil who would appear on TV speaking this godawful electronic-modulated voice. "I am the Scorcher. I burn your forests down." I was known to run screaming from the room when it came on the TV.
Smokey the Bear wasn't an angel either. This commercial scared the hell out of me back in the early 70s and it still is very disturbing today:

(I wasn't alone as there's actually a second version of this that's been reedited to be slightly less scary).
And then there was the TV trailer for It's Alive which looks funny today but scared the crap out of a 4-year-old:

I had nightmares about that one - in which, of course, the carriage kept rotating and some monster came shooting out of it towards me.
As I got older things like Scorchers and Joanna Cassidy taking her face off in a PSA didn't bug me. I tended to be more freaked out by the Emergency Broadcast System tests. I'm of the generation which was conditioned to expect the missiles coming over the horizon when this thing sounded for real, so you'll forgive me for getting pissed off the one time a TV station in Spokane activated it because 9-1-1 service had been distrupted, or recently when the Canadian version was activated for an Amber alert.
