Pooka (1990, Ashby-De-La-Zouch, Leicestershire)

A resident of the aforementioned village awoke in the middle of the night and witnessed what she believed to be a being known as a Pooka in Irish folklore, sleeping over the pelmet of a window on her landing. The creaeture looked similar to a small piglet, but had a long, pointy nose and no visible tail. Pookas are shapeshifting tricksters and mischief-makers in Irish faery lore, but as far as I know they have never been described as piglet-like entities.

Man-Horse (1994, King’s Lynn, Norfolk)

One late evening in 1994, the husband of correspondent Nicky Knott was driving home through King’s Lynn, Norfolk, down a lonely rural back road when he saw a large creature in a field to his right. As it moved closer, it seemed to be a horse, with equine body and four legs, but its observer was horrified to see that it had the face of a man! Terrified, Knott slammed his foot on the accelerator and sped away, and even though he was sure that the ‘thing’ was pursuing him he never once looked back till he reached home. Amazingly, this is not a unique case. Back in spring 1966, a creature fitting this same bizarre, man-faced, horse-bodied, centaur-reminiscent description was encountered in the road ahead as Margaret Johnson and her boyfriend John Farrell were driving past the estate of Lord Dillon in County Louth, Ireland, blocking their way for a couple of minutes and emanating palpable malevolence before abruptly vanishing. There is local mythology of a creature by the name of a 'Pooka' - one of which's forms resembles a monstrous horse. Obviously the connections between this sighting and the ancient centaurs do not need to be emphasised!
