Im not sure because it would have been in the 70s on HBO when I saw it but here it goes. What I can remember is a little boy about 11 or 12 back in the 17th or 18th century. Chritophor lee played a sort of priest of a town thinking the boy was a witch or trying to prove he was. The movie ended with I think two boys and one of the boys telling the other that his life wasn't real it was all a dream?? The movie is kind of hazy in my mind but would love to know the name of it if anyone can help.. good luck and thank you

The ones from the 70's start with a film entitled "1941," and go downward
From there. A plot summary for each one is shown. That should help
Identify it.
