I was reminded of something by another thread about Rod Serling's anthology series. There was also this, and it was scary folks.

In 1973 there was an anthology type movie shown on T.V. that scared the living daylights out of me. The film presents three allegedly true stories of the supernatural. The film was "Rod Serling’s Encounters with the Unknown". The part that sacred me the most was the second story of the film called "The Hole". I have seen other people my age (I was 7 in 1973) comment on how they had a similar reaction to it.
