Re Hammer Horror, I saw the first Christopher Lee Dracula at about 14 and still remember how unbelievably scary it was.
At the time I had a very old edition of Dracula, which had belonged to a granny - a hardback with a dark green cloth binding and ‘Dracula’ in a black, creepy Gothic script.
I couldn’t even sleep with that book in the room, in case it somehow summoned him! Had to keep my bedroom window closed in case he crawled in that way, as a bat!
I knew I was being utterly daft, but still couldn’t help it.
A school friend who saw it at the same time could hardly sleep for days afterwards.
