I too vaguely recall something quite terrifying happening in the sixties; but no details....memory like the proverbial sieve these days.
However, the hospital was regarded as being a frightening place before then. Two of my cousins lived quite near to the hospital and were occasionally terrified by the 'howling' they heard at night, born on the wind. Although I never disbelieved them, I had no idea, until I heard it for myself, just how frightening it was! The memory has haunted me ever since.....it is for me, the very epitome of a night-mare/horror-story. This would be around 1957-ish etc. I had spent the evening at my cousin's house; and was put to bed there for part of the evening, whilst our parents went to a 'do' at the Golf Club....they returned late, and I was bundled into the car whilst still half asleep, and was still semi-comatose as we were passing the drive-way to the hospital....but I soon woke-up!
For some reason, possibly road-works (?) we had to stop for a minute. Again, it was quite a windy night, and each time the wind gusted, there came the most spine-chilling wailing sound ...and amidst the howling, shouts, shrieks and wild laughter! It would rise and fade with the wind; and I don't mind admiting it, it put the fear of God into me! As we drove-off, I could tell that my father was purposely avoiding making any mention (my mother, being deaf, probably hadn't been aware of the noise) .... he couldn't NOT have heard it, so why didn't he say something??? This frightened me even more! I asked him what it had been, and at first he attempted to brush it off as unimportant, but then realised it just wouldn't do; so he explained about the ''poor souls'' who lived there, and that often they couldn't sleep when it was windy, and grew excited and made a noise. He said it was all perfectly normal, and nothing to worry about.....well, it didn't seem very 'normal' to me, and it DID worry me! Besides, I had seen my father's reaction when he heard the howling - he'd been 'spooked' too!
Up to that point I'd always loved the sound of the wind; my mother had told me never to be frightened by the howling of the wind during the night; as it was just ''God combing the loose twigs and branches from the trees''.....but following from that night, it was several years before I could relax, without fearing to hear those 'other sounds' riding the wind!
Looking back, it was all incredibly 'medieval' .... and decidedly too 'gothic' for my young mind!
