Here's my two cents on what scared me or gave me nightmares: Kolchak: The NIght Stalker Episode 6 "Firefall". The conductor, or should I say his doppelganger, tried to annoy Kolchak by repeatedly knocking against an open window of a church. It was that smirk and the insane look on his face with the knocking that bothered me as a little boy. I had nightmares about that doppelganger for a few days. Also from the 70s was that smiling cow on every bottle of Elmer's Glue. For some reason, I kept superimposing Mr. Clean's face with the cow and the two together had this I'm-going-to-get-you look. Weird and scary.
Lastly, any of the Bigfoot documentaries of the 70s. Chills down my spine all the time. It was hard to get any sleep. Oh yeah, I almost forgot: the neighborhood pedophile who always looked at me and my brother whenever we were out playing or going to the store. He was thin and tall like Norman Bates with sunken eyes and super creepy. I later discovered he had a record for molesting a neighborhood boy.
That's all folks! Keep up the Traumatic work.
