As a kid, "The Outer Limits" scared the hell out of me. That one more often than not had monsters you got to see, instead of just hinted at.
"The Twilight Zone" often was more cerebral had a moral to it, if you were a good person, you came out okay in the situation etc. Only episodes like "Time Enough at Last" and I forget the title, but the one with the young woman and her landlady held hostage by a home invader as the earth passes too close to the sun that had a major EOTW theme were kind of scary.
For Mrs. Dual, if it's late at night, and you start humming the theme to "Unsolved Mysteries",
DA DA DA DA DA... DOO DOO DOO DOO DOO!, and bellowing self-importantly, "
It was the night of April 12th, 1978..."
like the narrating Robert Stack in the trench coat, she gets the heebies...
