I remember several movies that freaked me out as a kid. Many of them were made for TV movies
Don't Be Afraid of the Dark
Trilogy of Terror
The Devil's Daughter
Salem's Lot (1979)
Crowhaven Farm
Horror At 37,000 Feet
I have them all on DVD. Watching these movies as an adult - some hold up and a few seem really hokey
