Tall ghost bites heads off swans? What film?

Hi this is my first post so forgive me if it's in the wrong section!

Over on IMDb there's an 'I Need To Know' thread where some guy is trying to find the the title of a horror film (possibly 90s) in which a young boy has visions of a tall entity biting the heads off swans, and now It's started to really bug me, so I'm hoping another horror fan will know the title of the film.

Sounds interesting doesn't it? I've searched using all the obvious combinations of words in google, but so far I've found nothing.

No clue really, but my best educated guess would be something Hammer or Giallo related tho that imagery is almost outside even those.

Maybe some other country made a movie inspired by the style of those. I don't expect this to be must help, but it's all I got.
