The lil guys from "Invasion of the Saucer Men!" I used to have nightmares of them waiting outside my bedroom window.
The monsters from "Island of Terror" also gave me nightmares and the scene where one drops out of a tree onto a person made me afraid to walk under trees at night.
I also had a friend who was absolutely terrified by Kaa, the snake from "Jungle Book" because he believed the snake had EATEN Winnie the Pooh (both characters having been voiced by Sterling Holloway). He cried every time he heard Pooh's voice coming from inside the snake. It's funny the stuff that'll scare kids that adults would never suspect.
