Hi there. My old daycare used to show films every month or so. One of these films scarred me for years. It was about trolls. It listed categories of trolls. Some dug cavities in your teeth with pickaxes. Some walked around with their head under their arm. The scariest for me was the one who snuck into your room while you slept and twist your fingers. No matter how much you hurt, the troll would keep twisting, and you wouldn’t wake up. That film had me sleeping with my hands under the covers for years. What the heck was my daycare showing us? Any idea? This was in the late ‘70s and early ‘80s, if that helps.
