I must have been in my teens when I first saw this series (in Australia), but it left a very strong impression. I was reminded of Worlds Beyond last weekend when I saw "Ringu (1998)", which was the first horror film to scare me anywhere near as much as these British TV classics.

I can't recall much more about this series except the opening music, which alone made my spine tingle. I also recall enjoying the episode entitled "suffer little children" episode and another one I vaguely recall about about a dance hall haunted by soldiers.

I recommend this for fans of ghost stories, but I have no idea where you might find it.
