The fear of the full moon goes back as far as when the first man walked on this planet. It's got nothing to to with the grvitational pull of the moon but rather that the reflected light of the sun will encourage the dead to rise from their graves and the spirits of the afterlife to come abroad.
The effect of this on fish can be remarkable and will cause them to go off feed.
There are strange paranormal lines of force that cross at a part of Greater Manchester, east of Eaton Hall, along the A576 near the village of Rhodes. It is said that the ghostly re-incarnation of Rasputin lives there, in a cave, together with his only companions, two polecats and an owl.
On moonlit nights, this apparition can be seen, dressed in a black monk's habit. The noise it makes is truly awful.
This eldritch figure has also been seen at the source of The River Kimb at a place called Dropping Well, so named because a member of an ancient order of witches of the Nether Haugh Hob, cured herself of the groaning squits in the year 1218.
The Ley line of Rhodes is connected to the Dropping Well Rock of course.
Beware ye the moonlit nights forsooth.
