Horror-ish things that scared me most (due to age/circumstances) were:
Day of the Triffids (the tv series)
Beneath the Planet of the Apes (had to sleep with the light on for 2 weeks)
Raw Meat (aka Deathline)
The Creeping Flesh
The Terror at Hell House (basically same story as The Haunting, with Delia Derbyshire soundtrack)
Threads (vague, surpressed memories of this - haven't seen it since it was on tv)
Don't Look Now
...probably more
